ARWD / A3RWD

ARWD is a single-phase autotransformer fan speed regulator whereas A3RWD is a three-phase autotransformer fan speed regulator. Both are applicable to voltage-controllable motors (230 V, 50/60 Hz) to control the rotational speed of fans and ventilation systems. Regulators are equipped with two indicators – the green one shows when the regulator is on while the red one shows when the TK contact is on. For better protection of the regulators, we suggest using overcurrent protection.

These controllers make it possible to select two optimal motor speeds and to switch these with a contact. Important energy savings and an increase of comfort can be achieved, for example by day and night control. Regulators are fitted with TK contacts for thermal motor protection and run/stop contacts (CC-closed/OC-open) for external or remote starting and stopping.

The transformers are made with Class II insulation and protection grade IP21 (A3RWD, ARWD 14) or IP54 (ARWD 1,5 – 10), maximum ambient temperature 40°C (ARWD) and 25°C (A3RWD), thermal class of insulation B (130°C). Manufactured in compliance with EN 61558-2-13.

Rated current SEC: 1,5 – 14 A
Rated voltage PRI: 230V 50/60Hz or 3x400V 50/60Hz
Rated voltage SEC: 5-step regulation

ARWE is an autotransformer fan speed controller dedicated for single-phase AC motor in ventilation and heating systems.The controller provides a 5-step output voltage regulation due to 0-10V DC input signal. A PCB power-electronic module measures external signal and switches on a relay on particular autotransformers tap according to signals level.

ARWE is equipped with an iternal controll unit that prevents the device from switching on two relays in othe same time (anti-shortcircuit system). The transformers are made with Class II insulation and protectiongrade IP54,maximum ambient temperature 40°C, thermal class of insulation B (130°C).Manufactured in compliance with EN 61558-2-13.

Power supply: 230V AC 50Hz
Output current: 1,5A ; 2A; 3A ; 5A ; 7A; 10A
Control: autamatic control by 0-10V DC signal

ARWE is a fan speed regulator dedicated for controlling single-phase AC motors in ventilation and heating systems by 0-10 VDC input signal and for operating in tandem with ZSE5 S or PSE5 TP controllers.

PSE5 TP controller is distinguished by its modern design, ergonomic touch screen and many available options. PSE5 TP is equipped with thermostat and two programs (7-day and 5+2 for week days and weekend) that enable precise temperature setting, according to client’s needs.

PSE5 TP and ZSE5 S controllers offer manual, 5-step regulation of a single or a group of ventilators and heaters. The ARWE regulator provides a 5-step output voltage regulation due to 0-10 VDC input signal. A PCB power-electronic module measures external signal and switches on a relay on particular autotransformers tap according to signals level.

ARWE is equipped with an internal control unit that prevents the device from switching on two relays in the same time (anti-short circuit system). The ARWE regulators are made with Class II insulation and protection grade IP54 for maximum ambient temperature 40°C. Thermal class of insulation: B(130°C). ARWE are manufactured in compliance with EN 61558-2-13.

Power supply: 230V AC 50 Hz
Current output: 1,5A; 2A; 3A; 5A; 7A; 10A
Control: automatic 0-10V DC
