MAIN TECHNICAL DATA

BRIEF DESCRIPTION

The TRF-220/12-25 K transformer is designed for safe ~12 V voltage power supply to domestic fans.

TRF-220/12-25 K - basic model, fig. 3;

TRF-220/12-25 KV - modification with a pull-cord switch, fig. 3;

TRF-220/12-25 KT - modification with a run-out timer adjusted from 2 to 30 minutes, fig. 4;

TRF-220/12-25 KTH - modification with a run-out timer adjusted from 2 to 30 minutes and a humidity sensor

with the set point adjusted from 60% up to 90%, fig. 4;

TRF-220/12-25 KTP - modification with a run-out timer adjusted from 2 to 30 minutes and a motion sensor

with sensitivity area 1-4 meters and viewing angle up to 100° fig. 4.

Due to constant improvements the design of some models may slightly differ from those ones described

in this manual.

OPERATION REQUIREMENTS

The transformer is designed for connection to 220…240 V 50/60 Hz power mains and is rated for continuous

operation always connected to power mains.

The product is rated for operation at the ambient temperature ranging from +1 °C up to +45 °C.

The product requires no grounding.

CONTROL LOGIC

TRF-220/12-25 KT - the transformer supplies voltage to the connected fan after an external switch

(i.e., light switch) supplies control signal to the input terminal LT. After control voltage is off, the transformer

continues to supply voltage to the fan within the time period set with the timer.

TRF-220/12-25 KTH - the transformer supplies voltage to the connected fan after an external switch

(i.e., light switch) supplies control signal to the input terminal LT or if indoor humidity exceeds the set point.

After control voltage is off or after humidity drops down below the set point, the transformer continues to

supply voltage to the fan within the time period set with the timer.

TRF-220/12-25 KTP - the transformer supplies voltage to the connected fan after motion detection at the

distance from 1 to 4 m with the horizontal viewing angle of 100°.

After no more motion is detected, the transformer continues to supply voltage to the fan within the time

period set with the timer.

To adjust the power voltage supply turn-off delay time from 2 to 30 minutes, turn the control knob T

clockwise to increase and counter-clockwise to decrease the turn-off delay time respectively, fig. 16.

To adjust the humidity set point from 60% up to 90%, turn the control knob H clockwise to increase and

counter-clockwise to decrease the humidity threshold respectively, fig. 16.

Warning! The transformer circuit is under mains voltage. Disconnect the product from power mains prior to

any adjustment operations. The delivery set includes a specially designed plastic screwdriver for the

transformer settings adjustments. Use the screwdriver to change the turn-off delay time or the humidity

set point.

Do not use a metal screwdriver, knife, etc. for adjustment operations not to damage the circuit board, fig. 16.

MOUNTING

The transformer is designed for wall surface mounting and is fixed with screws and dowels supplied with

the product. Do not install the transformer in humid environments.

The transformer and domestic fan mounting example is shown in fig. 2.

The transformer mounting sequence is shown in fig. 5-10.

The wiring diagram is shown in fig. 11-15.

The TRF 200/12-25 KV model is shown in fig. 15.

MAINTENANCE

Clean the product from any dust and dirt which may accumulate on the surfaces once in 6 months, fig. 17-19.

Disconnect the transformer from power mains prior to any maintenance operations.

To clean the transformer use a soft cloth and a brush wetted in a neutral detergent solution.

Avoid water dripping on the electric components, fig. 20. Wipe the surfaces dry after cleaning.
