RTRE 5 – Manual Five-Step Transformer With Motor Protection 5 Amp – 1 Phase – Systemair

Manual five-step transformer (with motor protection)

Manual five-step transformer (with motor protection)

A single-phase transformer which controls the fan speed by altering the supply voltage in five fixed steps.

The unit has input terminals for room thermostat RT, which stops the supply voltage to the fan when the circuit is broken.

These terminals are linked before delivery. The transformer has 230V terminals for operating dampers, electric water-heater batteries or other external equipment. These terminals have no current when the transformer knob is in position 0, or when the TK or RT input is open.

The indicator lamp on the front shows when the transformer is in operation. The fuse may be reset from outside. The RTRE has a self-extinguishing thermoplastic casing. Supply voltage: 230V 50/60Hz.
