INTRODUCTION
Power+ is a drive designed to control compressors with sensorless-brushless permanent magnet motors (BLDC/BLAC)
or asynchronous induction motors. It is fitted for panel installation or with heat sink outside of the panel. Configuration
and programming, as well as the run/stop controls and speed reference, are managed by a CAREL pCO controller or any
controller device via RS485 serial connection using the Modbus® protocol in master mode.
2.1
Functions and main features
In summary:
•
compact dimensions for assembly in electrical panels;
•
operation at ambient temperatures from -20 to 60°C;
•
can be installed in residential and industrial environments;
•
connection via serial network to Master programmable controller;
•
network address can be configured by setting the dipswitches inside to the drive;
•
can control various types of compressors;
•
DCbus output power supply for external auxiliary devices;
•
class B (in accordance with EN/UL 60730) and class R.1 (in accordance with EN/UL 60335-1) software for machine
safety management;
•
integrated motor protection (only for models which specify it);
•
STO (Safe Torque Off ) safety digital input for system protection;
•
panel installation or with heat sink outside of the panel, to optimise the dissipation of heat inside the electrical
panel;
•
programmable acceleration curve to adapt to the required specifications when starting compressor;
•
high switching frequency to limit motor noise;
•
detailed information on drive status via numerous read-only variables;
•
protection functions for the drive (short-circuit, overcurrent, earth fault, overvoltage and undervoltage on the bus,
overtemperature, overload), motor/compressor (overload and limitation of current delivered, locked rotor) and
system (communication failure);
•
Coldplate models to be thermal coupled to an auxiliary cooling device.
