2.4 Input voltage of phases: 380V/ 220V.
2.5 High voltage, low voltage protection.
2.6 Controller operation power supply:AC16-28V,15VA
2.7 Measurement :
2.7.1 DISC T:-50~350a ,Accuracy:A 1a .
2.7.2 Running time:0~999999hours.
2.7.3 Current:0~999.9A.
2.7.4 Pressure:0~1.60MPa.Accuracy;0.01Mpa.
2.8 Phase anti-reversal protection: When compressor is at stop mode and detects phase reversal, response timea 1s
2.9 Motor protection: This controller provides open phase, unbalance and overload protection to motor, and also, provides overload protection to fan.
2.9.1, Open phase protection:When any phase opens, the response time equals to set time;This function is not activated when OPEN PHASE PROTECTION time is set over 20s
2.9.2, Unbalance protection: when MAX-MIN current >= SET DATA *MIN current/10 ,respond time is 5s;
2.9.3, Protection features of overload (time unit: second),please see following table(table 2.9.3.1)for your reference. Multiple=Iactual/Iset ,response time is shown in following table (table 2.9.3.1) according to overload multiples from 1.2 times and 3.0 times .
Iactual/Iset

Table 2.9.3.1 curve table for protection of motor
2.10 Temperature protection: when actual temperature measured is higher than temperature set; response timea 2s;
2.11 Contact capacity of output relay: 250V,5A;Contact endurance :500000 times
2.12 Current error is less than 1.0%.;
2.122 points of RS485communication port. 1 point is for block mode or computer communication.
The other point is for inverter communication like reading inverter run parameter, controlling inverter on-off or adjusting inverter frequency.
2.14 Remote control compressor: When set as REMOTE, user can remotely control the compressor.
