Panasonic Relay, Dpst-No, 400Vdc, 20A; Contact Configuration Panasonic HEV2AN-P-DC15V

The Panasonic relay, part number 72W3941, is a double-pole single-throw normally open (DPST-NO) relay designed for direct current applications. It has a maximum switching voltage of 400 VDC and can handle a contact current of up to 20 A. The relay features a compact size with dimensions of 41.0 mm x 50.0 mm x 39.4 mm and is suitable for through-hole mounting. This relay is RoHS compliant and has a flux-resistant protective construction, making it suitable for various applications, including photovoltaic power generation systems and battery charge/discharge systems. The coil voltage options include 6V, 9V, 12V, 15V, and 24V DC, with a pick-up voltage of 70% of the nominal voltage. The relay can operate effectively in ambient temperatures ranging from -40¬8C to +55¬8C, and it has a mechanical life expectancy of over 1 million operations. Engineers considering this relay should note its ability to contribute to energy savings through reduced coil hold voltage, which can be as low as 33% of the nominal voltage. The relay is also UL and VDE certified, ensuring compliance with safety standards.
