Shanghai Chaoshi Electronic & Electrical Equipment Co., Ltd.

Features:
· Both voltage and current protection in one product
· Used in conjunction with leakage protectors
· Simple and reliable protective circuit
· Convenient line detection
· High precision; low temperature drift
· Applicable to the protection of home-use charging devices and home-use power distribution equipment

Functions:
· Protection functions: Overcurrent, over-/undervoltage, electrification of zero line
· Alarm function of the indicator lights: Loss of ground wire, reverse connection of zero line & phase line; Indication by the indicator lights: Normal state, loss of phase line, loss of zero line
· Actuation time: When the overcurrent is over 25%, or when over-/undervoltage protection and electrification of zero line protection take actions, the actuation time of the protector is less than 3 seconds, in order to prevent malfunctions caused by voltage or curent fluctuation; When the overcurrent is smaller than 25%, the actuation time of the protector is less than 5 seconds. (Duration of the actuation time can be chosen based on the load magnitude.)
· Delay recovery: After the protector acted, it will delay for 3min before getting back to work, and it will reset the power. (Depending on different control circuits, there is probably no delay recovery process.)
· Protection against backlash voltage during undervoltage protection: 2+1VAC
· Leakage current for driving the leakage protector: <30mA
· Accuracy of voltage setting: <0.5% (Set value x 0.5%);
Temperature drift: <0.05V/℃ (Benchmark temperature: 25℃)
