General descriptions:
ECB-20 is a new optimizing product especially designed for refrigerant units. Double-sensor control, proper and complete protection functions. Easy-to-operate, stable and reliable performance. ECB-20 is an Electric Control Box with multi-functions and rather high performance versus price ratio
Main functions and parameters:
◆Power supply: Three-phase five-wire (or three-phase four-wire), 380 VAC ±10%, 50Hz
◆Technical parameters:
◇Temperature measuring and controlling range: -40~50℃
◇Accuracy: ±1℃
◇Compressor start-up delay protection time: 0~9 minutes (Adjustable)
◇Max. capacity of controlling the compressor and fan: 5.5 11 15
◇Max. capacity of controlling the defroster: 5.5 7.5
◆Functions and features:
◇Double-menu management mode: user's menu and manager's menu setting. Common user only
need to set the temperature and return difference
◇Double temperature measuring sensors to independently control the temperature of compressor
and defroster, more safe and economic
◇Single-point temperature calibration, return difference for temperature controlling, easier-to-operate
◇Comprehensive protection function of compressor
◇Auto and manual control function
◇Sensor error alarm and alarm when exceeding the temperature limits functions
◇Compressor start-up delay adjustable
