5.4 Compressor Motor
• This unit uses an inverter-controlled DC compressor. The compressor motor is operated by
three-phase voltage outputted from the STI module on the relay board.
Specifications:
- Rated Voltage: DC 220 V
- Rated Output: 1380 W
5.5 Compressor Overload Relay
• An external compressor overload relay is used
to protect the compressor motor. This relay is
mounted within the connector housing that
attaches to the top of the compressor. The
relay interrupts high temperature build-up in
the compressor.
Specifications:
5.6 Evaporator Fan Motor
• This unit uses an inverter-controlled DC
evaporator fan motor.
• The evaporator fan motor is operated by DC
motor actuation voltage outputted by the relay
board. Evaporator fan motor speed is
controlled by a relay board built into the fan
motor.
Specifications:
- Rated Voltage: DC 325 V
- Rated Output: High - 240 W, Low - 104 W
- Rotational Speed: High - 935 rpm, Low - 750 rpm
