What this power supply replaces

This replacement unit matches the Delta DPS-300AB-81B and FSP FSP350-20GSV models used in hard-disk recorders. It delivers up to 350 W of DC output for those specific devices.

What to verify before ordering

Confirm that your recorder’s existing unit is labelled DPS-300AB-81B or FSP350-20GSV and that the connector layout in the product images matches yours exactly. The input range covers 100-240 V at 50-60 Hz with a 52 A rating, so mains compatibility is broad.

Behaviour under sustained load

Each unit passes a factory quality inspection before shipping, ensuring stable 350 W delivery during continuous recorder operation. The design targets reliable long-term performance rather than short peak bursts.
