 Input voltage: 3 phase 380V±15%, 2.2kw to 75kw
 Pressure signal reference: external analog 0-10V, 0-1A.
 Protection function: Input phase missing, input under voltage, over voltage, over current, over load, over heat, external disturbing .
 Cooling method: force cooling
 Mount: Wall mount
 Function features
 Energy saving: up to 60% energy saving compare to traditional fixed pump system. 75% is possible be achieved according to difference injection condition.
 Lower oil temperature: reduce 5-10 degrees
 High repeated accuracy: To achieve high accuracy flow and pressure control
 Long pressure holding time: It is favorable for big wall thickness.
 Quick response: frequency response up to 50ms.
