“Power+” +0300050EN - rel. 2.3 - 08.06.2012 8
2. INTRODUCTION
Power+ is a drive designed to control compressors with sensorless-brushless
permanent magnet (PM) motors (BLDC/BLAC) or asynchronous induction
motors. For the latter, vector or V/f control can be selected. The drives can
also be used in some applications with fans and pumps, and consequently
the device o ers exible use in the air-conditioning and refrigeration
sectors. It is tted for panel installation or with heat sink outside of the panel.
Con 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.
To suppress current harmonics:
• on single-phase models, during installation a toroidal coil, supplied with
the drive, needs to be connected for active power factor correction (PFC);
• on three-phase models, connection of a DC choke is optional (available for
purchase as an accessory), if compliance with EN61000-3-12 is required.
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 con gured by setting the dipswitches directly on
the drive;
• can control various types of compressors;
• safety digital input (Safety Torque O );
• dedicated input for PTC thermistor or thermostat to monitor motor
overtemperature;
• panel installation or with heat sink outside of the panel, to optimize 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 speci 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 (Safety
Torque O input, communication failure).
2.2 Models
The models di er due to power supply and rated output current as well as
for type of cooling:
• traditional with forced air cooled nned heatsink – frame sizes 1 and 2.
• coldplate, with plate for coupling to auxiliary cooling circuit devices (not
supplied) – frame size 3
