The "HV500" is a high-voltage contactor that achieves a maximum voltage of 1,000 volts and complete hermetic sealing. It is part of the high-voltage series from Olbright, which is directly compatible with existing contactors on the market. It enables durability in harsh environments and operation in potentially hazardous conditions. If equipped with a PWM circuit, this circuit is also sealed. 【Features】 ■ Completely sealed type (complete hermetic seal) ■ Non-polar sensitive ■ PWM coil economizer option ■ Coil reverse polarity protection function ■ Auxiliary switch - normally open (a contact) or normally closed (b contact) option ■ Magnetic latch option *For more details, please download the PDF or feel free to contact us.
