    ESM External Wired Energy-Saving Module

    External Wired Module | Zero Heat Rise | 80% Energy Savings | AC/DC Universal | Noise Suppression

    • Flexible Installation: Hard-wired external design can be series-connected at any point in the circuit; fits inside control boxes or valve terminal housings.

    • Thermal Control: Eliminates coil temperature rise, maintaining operation at near-ambient levels (slightly above room temp) even during 24/7 activation.

    • High Efficiency: Reduces holding power consumption to just 20% of the original rated power.

    • Enhanced Stability: Ensures reliable pull-in even with 25% voltage fluctuations; functional at low AC voltages (as low as 170V).

    • Silent Performance: Zero electromagnetic hum or buzzing, providing a stable and quiet industrial environment.

    • Universal Application: Upgrade solution for high-temperature valves | explosion-proof solenoids | irrigation systems | CNC automation.

    • Compatible Alternative for:

      • ASCO / Burkert / SMC systems requiring extended energization.

      • Any standard solenoid coil prone to overheating or burnout.
