Core Insulation

Core

● Standard wire leads : UL1015(600V/105°C) or UL1331(600V/150°C)● Primary leads covered with secondary sleeve : double insulation

● Tape wound type : Standard two layers polyester film Class B(130°C)

● Reduces capacitive coupling between primary and secondary windings● Copper foil(35μm) laminated with polyester film

● Four layer minimum between windings with polyester film Class B(130°C)● Meet test requirement of 4,000Vrms for 1 minute between primary and secondary

● UL approved Double Coated Polyamide-imide (200°C), considered hot-spot in winding● Windings configured for minimum flux leakage and reduced distributed capacitance

● Usually in primary circuit● Normally closed-auto reset, opens at high temperature

● 100% surface coverage of two layers of 50μm polyester film Class B(130°C)

● Circular cross sectional iron core without sharp corners... no core caps necessary● Continuous tightly wound grain oriented silicon steel strip... no air gap, no mechanical noise

Considerations in Using

Shorted Turn Condition

Transformer Rating Suggested ProtectionUp to 300VA None300VA to 1,000VA Use slow-blow fuse in primary circuit1,000VA to 2,000VA Add a small value resistor in series with primary circuit2,000VA and up Relay momentarily inserts resistor in primary circuit at start-up, or NTC Thermistors

Temperature Rise

Duty Cycle

RegulationThe load regulation of torus transformers is expressed by the following equation:%Reg = 100 x (V_no_load - V_full_load) / V_full_load

Rectifier Circuits

Full Wave Bridge Full Wave Center Tap

A completed path by any conductor passing through the center hole of the torus transformer around the outside constitutesa short circuited turn. As with any short circuit, this condition will result in high circulating currents and, more importantly, high heat.

The excellent magnetic properties of the torus transformer and the high remanence of the grain-oriented silicon steel, under certain circumstances, occasionally leads to high inrush current at turn-on.To prevent nuisance interruptions due to blown fuses or supply breakers, some simple precautions should be considered. As the power rating of the transformer increases, the potential effect of the inrush current becomes greater. The following table suggests different types of circuit protection according to the transformer power rating.

Torus transformers are ordinarily designed to render a 60℃ to 65 ℃ temperature rise. The graph on the right illustrates the rise in transformer temperature as the actual power approaches and then exceeds the transformer’s nominal power rating. Careful consideration must be given to the expected load conditions.

A significant reduction in transformer size and weight may be realized in many cases where the transformer is loaded intermittently. In such cases, the load is energized for a small portion of the period. If the loaded period is much shorter than the overall thermal time constant of the transformer, Refer to the equation on the right:

When used in rectifier circuits, the advantages of transformer may be optimized if consideration is given to how they are applied. AC current in the transformer’s secondary is not only influenced by the DC load current, but, just as important, by the circuit configuration. Common circuit configurations are shown as follows:
