“Power+” +0500048IE - rel 2.2 - 06.11.2014
ENG
2. INTRODUCTION
Power+ is a drive designed to control compressors with sensorless-brushless permanent magnet motors (BLDC/
BLAC) or asynchronous induction motors. The drives can also be used in some applications with fans and pumps,
and consequently the device off ers fl exible use in the air-conditioning and refrigeration sectors. It is fi tted for panel
installation or with heat sink outside of the panel. Confi guration 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 confi gured by setting the dipswitches inside to the drive;
• can control various types of compressors;
• safety digital input (Safe Torque Off );
• dedicated input for PTC thermistor or thermostat to monitor motor overtemperature;
• panel installation or with heat sink outside of the panel, to optimise the dissipation of heat inside the electrical
panel;
• electrical connections can be made without needing to remove the plastic cover;
• programmable acceleration curve to adapt to the required specifi cations 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), motor (overtemperature and limitation of current delivered) and system (Safe Torque Off input,
communication failure).
• Coldplate models to be thermal coupled to an auxiliary cooling device;
