COST EFFECTIVEBest-in-class features, benefits and capabilities without any premium.
The hand-held provides the means to utilise all of SIGMALT’s unique and exciting features including:
Remote control of load banksTouch screen controlNetwork and control load banks togetherIndividual load control in the networkUSB Data loggingFast and accurate load controlSynchronous load changesSingle or three phase instrumentation1kW load resolution on selected modelsSimple firmware updates
SIGMALT also includes digital toggle switches for simple, local control and the SIGMA gateway for integration with existing control systems.

480 0 60 0 0 0The hand-held is a touch screen remote control encased in a robust aluminium enclosure enabling the user to optimise and maximise all SIGMALT features and benefits.
Digital toggle switches are fitted to all SIGMALT load banks and offer simple local control. This method of control is perfect for quick load tests and useful as a local backup to the hand-held.
WARNING
SIGMA GATEWAYThe SIGMA gateway connects to the load bank control panel and provides a means of communication over Ethernet. This method is for the integration of SIGMALT load banks to existing PLC or BMS control systems that are common in many load bank applications.
FEATURES BENEFITS
Individual remote control of a load bank.
• Observe the supply-on-test whilst applying load and viewing instrumentation without the need to return to the load bank.
• Control the load bank from up to 250m away.• No reaching down to the load bank to change load.• Fine 1kW load resolution on selected models.
25 load banks can be connected in a networkand controlled by a single hand-held.
• Small load banks can be networked to provide high capacity testing in places a larger load bank cannot be used e.g. roofs and basements.
• Fine load resolution can be achieved on high capacity tests.• A single operator can control 25 load banks with no assistance.• Firmware can be updated on all load banks connected to the
network.• Supports n+1 load bank redundancy if a problem occurs.
One hand-held enables control of ALL or INDIVIDUAL load banks in the network.
• Provides differing loads to specific load bank locations i.e. data centre HVAC testing can require precise load in various areas of the hall.
• Load can be applied to any load bank/s in the network to test various sized supplies at one time.
Log test data onto a USB flash drive.
• Open in spreadsheet software to create reports and certificates of test data.
• The data can be analysed, dated and filed for comparisons against previous tests.
• Prove a generators performance with backed up data.• If the supply-on-test fails, specific load, times and dates are
logged to refer back to.
4.3” full colour touch screen control encased in robust aluminium.
• The intuitive user interface allows load testing to be fast and simple with a small learning curve.
• The touch screen has a long operational life.• The aluminium enclosure ensures the hand-held is robust
enough to endure typical load test applications.
Modular design.
• Switch between digital toggles and the hand-held with the press of a button.
• Add or remove load banks to the network quickly and simply to increase or decrease the available capacity.
CAN bus network protocol.• Fast network connectivity for quick load changes and reliable
testing.• 20% faster load changes than the nearest competitor.
FEATURES BENEFITS
Digital, single or threephase instrumentation.
• Cycle between available instrumentation: 3 phase Voltage and Currents or Voltage, Frequency and power.
• Bright LED display with digital accuracy.• Toggle between single and three phase modes.
Superior accuracy.
• Correct load is applied whether in single or three phase mode.• Improved load accuracy in dual Voltage (240/480V) versions.• Limit the load to prevent accidental overloading of the supply-
on-test.
Synchronous load changes.
• Unlike traditional toggle switches, load changes that require multiple steps are applied instantaneously.
• Important for generator AVR and Governor testing.
Easily expandable. • Simply connect the hand-held to utilise the enhanced features it has to offer.
Reliability and longevity.• The digital toggles are rated as having an operational life 10
times that of standard toggle switches. (10,000 vs 100,000 actuations).
FEATURES BENEFITS
Connectivity from SIGMALT
to Ethernet.
• Provides integration into most existing PLC and BMS control systems.
• Compact box can be easily connected and disconnected to the load bank.
• Network up to 25 SIGMALT load banks.• Provides the same features as the hand-held through a single
Ethernet port.

TYPICAL APPLICATIONSSIGMALT load banks are built to offer a range of features to suit any application. The feature rich hand-held provides a means of utilising all features and the digital toggle switches provide fast local control. Alternatively use the SIGMA Gateway to integrate the loads banks into an existing BMS or PLC control system.
MISSION CRITICALThe importance of back-up power in a mission critical environment is paramount. Regular maintenance plans are vital in keeping gen-sets and UPS systems in full working order and that back-up power will run correctly if required. SIGMALT not only provides a means of applying load and maintaining the gen-set as part of the maintenance programme but also allows test data to be captured, analysed and saved for future reference. A full list of test results can be catalogued and compared in the future to keep track of the health of a gen-set or UPS.
DATA CENTRESData Centre heating, ventilation and air conditioning (HVAC) systems must maintain a constant temperature to prevent servers from overheating and causing damage. SIGMALT load banks can effectively simulate server heat discharge HVAC systems may encounter. Up to 25 SIGMALT load banks can be strategically placed in a Data Centre hall and controlled by a single hand-held. Load can be applied proportionally to all load banks in the network to provide a uniform temperature rise or alternatively, load can be adjusted on specific load banks. This unique individual load bank control allows the simulation of hot spots to analyse the reaction of the HVAC system in that particular area. Test data can be logged to a USB flash drive and opened in PC spreadsheet software for analysis. For Data Centres that already have building management systems (BMS) in place, the SIGMA Gateway can be used. The SIGMA Gateway allows integration of control through Ethernet and works with most PLC and BMS systems.
RENTAL/SERVICEVersatility is key for rental and service businesses and brings challenges with differing voltages, capacities and applications. SIGMALT provides the ultimate flexibility. Connect up to 25 load banks together to increase testing capacity for a high capacity tests or alternatively use a single load bank for a smaller test. This allows for a very flexible fleet, optimum utilisation and higher returns on investments made. Operate either the digital toggle switches for simple single load bank testing or the hand-held for networking and data logging on more complex load test applications.
GEN-SET MAINTENANCESIGMALT provides the perfect test environment for regular gen-set maintenance programmes. The Digital Toggle switches provide local control to quickly and accurately apply load. Load can be selected and applied in a matter of seconds and the synchronous load step changes mean the gen-set has the correct load instantly. For generators with higher capacities connect up to 25 load banks in network and control by a single hand-held. The hand-held is able to log the test data to a USB flash drive and then can be used to compare future tests and create a database of the health of the gen-set over time.
RENEWABLE ENERGYThe amount of electricity wind and solar farms produce depends on the weather. On an extremely windy day, a wind turbine will produce more electricity than is able to be put onto the grid. Load banks are an effective way of dissipating this excess power and preventing the turbine from overloading. The SIGMALT hand-held allows load banks to be connected in a network to increase the capacity and effectively meet the dissipation demands. Many wind and solar farms already have an existing centralised control system. SIGMA Gateway provides a method of integrating the load banks into that control system for ease of use.
