This 250W CRPS hot-plug redundant switching power supply is a fully compatible replacement module for Delta original DPS-250AB-81 A and DPS-250AB-81 B, widely applied to rack-mounted DVR, CVR surveillance recorders, NAS network storage and mini rack servers.
Designed to comply with CRPS industrial redundant power specifications, it supports 1+1 dual power parallel operation. When one power supply fails, the other instantly takes over the full load without shutting down recording or storage services, effectively preventing data loss caused by power faults.
Equipped with Active PFC circuit, it delivers high energy efficiency and reduces heat generation under full load. The wide-range 100-240V AC input adapts to power grids worldwide without extra voltage converters, providing steady 12V main power and 24V auxiliary power for multi-channel camera mainboards and large-capacity hard disk groups.
Integrated multi-layer intelligent protection circuits will immediately cut off output when overload, short circuit or overheating occurs to avoid permanent damage to core storage and monitoring hardware. The gold-plated CRPS communication connector supports PMBus protocol, enabling remote real-time viewing of voltage, current and fault status for convenient IT centralized management.
With an integrated quick-release pull tab, maintenance staff can hot-swap the faulty power supply without powering off the entire rack device. The variable-speed cooling fan automatically adjusts speed according to internal temperature to lower noise during light-load standby.
Every power supply passes strict full-load aging, ripple and shock testing before delivery, and meets UL, CE, FCC safety certification standards. The reinforced metal casing with dense honeycomb ventilation holes optimizes heat dissipation, perfectly suitable for long-term continuous operation in monitoring machine rooms, small data cabinets and industrial rack equipment.
