Transformer regulators
Five-stage transformer speed controllers are designed to control asynchronous squirrel-cage motors, which are recommended by the manufacturer. Manually operated controllers have a switch on the front panel. In the version with remote control, the controller is supplemented by five contactors, which are interlocked. The remote control is provided by simple controls that allow Start, Stop of the fan, signal Standby mode and some even allow speed setting. With a controller with a voltage converter, it is possible to program the levels at which switching takes place, the hysteresis of individual stages and the time between switching from one stage to another. When switching, all stages are switched off first and with a time delay (programmatically 6 to 600 sec) the next stage is switched on.

RE / REU
The RE / REU transformer speed controllers are 5-stage fan speed controllers with a supply voltage of 230V and without TK thermal contacts. The fan speed is controlled by changing the output voltage using a switch on the front plate of the transformer. The RE / REU auto-transformer speed controllers are equipped with indicators for operation signaling.
REV / RDV
The REV / RDV auto-transformer speed controllers are designed for the control of asynchronous squirrel-cage motors. The REV / RDV A controllers are equipped with a power 5-stage switch, controlled by a switch on the housing. The REV / RDV C auto-transformer controllers are speed controllers with 5 stage output switching by contactors, controlled by a remote communication switch DOC or DO signal from the parent digital system. The REV / RDV E controllers are contactor switched, equipped with a voltage converter and a 24V AC/DC source for the analog sensor.
RTRE / RTRD / RTRDU
The RTRE / RTRD transformer speed controllers are 5-stage fan speed switches with supply voltage of 230V / 400V, speed control is performed using a switch on the front of the transformer. The RTRDU transformer speed controllers are designed for fans with a supply voltage of 400V, speed control is performed using two switches on the front.
TRN / TRRD / TRRE
The TRN / TRRD / TRRE auto-transformer five-stage speed controllers are designed for switching fans of the type RP, RQ, RO, RF. The TRN five-stage controllers have a separate control (ORe) and power part, which are interconnected by a cable. The TRRD 5-stage controllers are equipped with switches on the front panel of the controller. It is necessary to use an STD protection relay for the controllers. The TRRE five-stage controllers are designed for single-phase fans. The controllers have a built-in control and power section. The controllers must be equipped with a STE protection relay.
RMT
The RMT five-speed speed controllers are made of ABS plastic (RMT 1.5 and RMT 2.5), RMT 5, RMT 8 and RMT 12 are made of metal. The RMT are designed to control 400V fans. the RMT auto-transformer speed controllers are equipped with a power 5-stage switch 90, 150, 200, 280, 400V, which is controlled by a switch on the housing (START / STOP).
