Can also be used in uninterruptible power supply and other electronic control systems. Are available with Sealed IP67, gas-filled relay which mitigates arcing polarized and non-polarized contacts to best suit electrical No mounting orientation restrictions systems polarity. The Coil Economizer greatly reduces coil Designed and manufactured under the IATF16949 power and heating after the contactor is energized. Once the certification for Automotive Quality Systems. contactor is energized, it takes minimal coil power to keep Designed specifically for automotive applications. the contacts closed due to Pulse Width Modulation (PWM) reducing the average power delivered by pulsing the electrical signal.
