Es low power energy saving coil(AC220V 3VA DC24V 3W)
Lead wire plastic seal
ES-series low power coil,advantages:
1. Can use on AC/DC solenoid valve,not change original solenoid valves structure
2. maintain low power,only 20% of normal coil power
3. Slowly heating-up under long-time power-on working status,
4. the coil’s temperature≤40℃, longer life time
5. Instant and strong electromagnetic attraction, 3 times more powerful than normal coil, enhance max working pressure
6. No abnormal noise when using AC voltage
