It delivers 200W of isolated 52.5V at 92% efficiency over voltage input range of 36V to 75V. Standard features are remote on/off, remote sense, trim capability, over-voltage, over-current and over-temperature protection. The HHS04-520 can operate in parallel for additional power with external circuitry. The HHS04-520 measures 2.40"(L) x 2.28"(W) x 0.43"(H) and has an operating temperature range of -40C to +100C.
