Shanghai Chaoshi Electronic & Electrical Equipment Co., Ltd.

Features:
· Used in three-phase AC variable-frequency voltage environment (such as in a variable-frequency VVVF elevator or in a medium-frequency furnace) in three-phase three-wire/four-wire AC circuits
· Power supply: low voltage 12V or 24V, applicable for both AC and DC
· Taking electricity is convenient
· Installation methods: Push-type spring terminals/Plug-type screw terminals
· Adaptability to abnormal wave form, anti-pulse capability, and anti-carrier capability in a powergrid with a poor power supply
· The low-voltage working power supply uses float ground design, isolated with three-phase AC voltage
· Resistance to high pressure, high frequencies, and pulse
· The protection check points can be placed either at the front/back end of the switch contacts, or the front/back end of AC contactors. If the check points are placed at the front end of the load, the protector offers effective protection to the circuit in front of the load.
· Contact output solution convenient for process control: After the low-voltage power supply is power-on, there are two options available for the relay contact output-suction (default) or non-suction (Model T)
· Accuracy of voltage setting:<0.5% (Set value x 0.5%);
Temperature drift:<0.05V/C (Benchmark temperature: 25C)


Functions:
· Protection fumctions: Overvoltage, undervoltage, phase sequence, dynamic phase loss, static phase loss, voltage unbalance
· Time delay functions: Delay output, delay recovery, power-on delay
· Protection against backlash voltage during undervoltage protection: 4+1VAC
· When the working voltage is DC, the protector has a protection function against reverse connection;
When the working voltage is low-voltage AC, the voltage is non-polarized.
