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 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.
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 confi gured by setting the dipswitches directly on
the drive;
•
can control various types of compressors;
•
safety digital input (Safety Torque Off );
•
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 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 (Safety
Torque Off input, communication failure).
2.2 Models
The models diff er due to power supply and rated output current as well as
for type of cooling:
• traditional with forced air cooled fi nned heatsink – frame sizes 1 and 2.
• coldplate, with plate for coupling to auxiliary cooling circuit devices (not
supplied) – frame size 3
