Humfree N&D Contactor 25A, 3NO, 230V

Energy Regulation Module This component is designed to monitor, regulate, and stabilize electrical current within a closed system. It ensures consistent voltage delivery across connected components while protecting sensitive circuits from surges or fluctuations. **Electrical Specifications:** Nominal operating voltage range: 12V-48V DC. Adjustable output threshold between 1.2V-36V using onboard trim potentiometer—preset at standard factory calibration of 5V. Rated for maximum current handling up to 10A continuous; short spikes tolerated up to 20A under defined conditions (not recommended for prolonged use). Ripple suppression capability ≤50mVp-p depending on load type. **Physical Design & Connections:** Form factor: Compact rectangular casing with heat-dissipative aluminum housing—passive convection cooling only; requires external airflow in high-load applications. Dimensions: Approx. 44mm x 30mm x 16mm excluding terminals/protrusions (verify fitment against known clearances). Integrated input/output screw-based terminal blocks accept conductor sizes ranging from AWG22–AWG14, secured via locking clamps for vibration resistance. **Operational Features:** Integrated temperature shutoff mechanism triggers at thermal overload >85°C case surface temperature—auto-restart after cooldown delay of ~60 seconds minimum (dependent on ambient conditions). Response time during load changes slightly variable but typically sub-15ms per shift; measurement deviations possible in poorly grounded setups due to external EMI noise factors. *Technical Notes & Limitations:* - Designed strictly for low-voltage DC systems; not compatible with AC supply inputs or mixed power environments involving inverter-fed sources. - Absence of IP-rated sealing makes unit unsuitable in high-moisture areas unless installed inside secondary enclosure rated >IP54 minimum protection level. - Potentiometer adjustment may void warranty if altered beyond manufacturer-specified limits documented during initial QC validation benchmarks testing procedures.
