Description
Albright HV500AF-38 – Hermetically Sealed Electromechanical High-Voltage DC Contactor
The Albright HV500AF-38 is an electromechanical, single-pole normally-open (SPST-NO) high-voltage DC contactor in the HV500 series. It uses physical main power contacts to connect and disconnect DC circuits; it is not a solid-state relay. This configuration uses a 48V DC control coil with PWM coil economiser. The stated 48V DC is the control-coil voltage, not the main circuit voltage.
Features
- Electromechanical DC switching with normally-open main contacts
- Hermetically sealed HV500 contactor construction
- HV500 series validated for applications up to 1000V DC, subject to application-specific switching ratings
- Thermal current rating up to 500A with appropriately sized conductors and installation conditions; switching ratings must be checked separately
- Non-polarity-sensitive main contacts
- PWM coil economiser
Typical applications
Designed for DC power switching in electric vehicle battery systems, charging equipment, renewable-energy systems, energy storage and industrial DC equipment, subject to electrical design and application verification.
Selection note: Verify load voltage, continuous and breaking current, coil supply, pre-charge requirements and control options against the exact Albright catalogue and application requirements. PWM electronics are used for the coil circuit, not for solid-state switching of the main current. The HV500 contactor is not a substitute for appropriately rated external circuit protection.
