Jvl-ir 380v-440v universal undervoltage protector
Product description
1、Overview:
This product is a complete set of electrical control equipment used for phase failure and undervoltage protection of various motors. It can be used on 380V / 440V three-phase power supply. When it is used, it shall be operated according to the provisions of this manual. When used as 440V three-phase power supply, only one of the three-phase wiring needs to be moved from the original wire on L3 to L3 'terminal (L3 terminal can be empty without wiring). If the two in-in terminals are short circuited, the control of undervoltage protection function can be set arbitrarily, and the control time will automatically restore the normal undervoltage protection function after 20s ± 10%. It is an indispensable protector for motors of different sizes and powers.
2、Main technical indicators:
1. Power supply: 380V ~ / 440V ~ 50Hz / 60Hz
2. Service temperature: - 20 ℃ / + 55 ℃, relative temperature ≤ 90%
3. Contact output: AC 250V / 5A
DC 30V/5A
4. Control time: 20s ± 10%
