Description
This product is a frequency inverter for fully variable control of compressors with a constant moment of torque. Suction pressure feedback is done via a pressure transducer with a 4 to 20 mA output signal and is connected directly to the inverter.
Features
- Enter evaporating pressure in bar
- Automatic low power shut off with configuration on/off time
- Integrated rack controller for controlling up to 3 additional compressors via integrated isolated output relays
- “ACC” rack controller with integrated base load switching for 2 compressors and ...
- Enter evaporating pressure in bar
- Automatic low power shut off with configuration on/off time
- Integrated rack controller for controlling up to 3 additional compressors via integrated isolated output relays
- “ACC” rack controller with integrated base load switching for 2 compressors and alternating control. One compressor is controlled, the 2nd compressor is activated via the network as required
- “TCC” rack controller with integrated base load switching for 2 compressors with alternating control. One or both condensers are operated as required
- Maximum number of starts per hour can be configured
- Compressor activation can be time-based or sequential
- Display of evaporating pressure in the system in bar
- Day/night switching option
- Peak load shedding by monitoring condensing pressure via a pressure transducer and connection to analogue input A3
- 0-10 V control output for controlling a condenser fan
- Intelligent oil sump heating by measuring the ambient temperature and adjustable temperature and time interval for operating the oil sump heater
- Oil return function for when output frequencies are too low operates the compressor at the nominal frequency for a configurable period of time
- Auto-Boost mode, unloaded start by exceeding a configurable evaporating pressure
- Auto shut-off in event of sudden pressure drop in system
- Maintenance mode, maintenance reminders after a configurable period of time
- The frequency inverter is pre-programmed for use with the majority of compressors without additional programming being necessary
