Product introduction
The Mean Well RSDH-150 series are compact, high-reliability DC-DC converters designed for ultra-high input environments (PV strings, battery stacks, HV telemetry, surveillance and industrial automation). Each model accepts an extremely wide DC input and delivers a single isolated low-voltage output (12, 24, 32 or 48 V) at up to 150 W — ideal where stable low-voltage rails are required from high-voltage sources.
Key benefits — why engineers pick RSDH-150
- Ultra-wide input (250–1500 Vdc)— supports string PV/battery and other high-voltage sources without extra front-end hardware.
- High isolation (4 kV AC)for safe separation between input and output in harsh installations.
- Compact chassis-mount form factorthat fits constrained enclosures (191 × 86 × 41 mm).
- Wide operating range −40 °C to +80 °Cand altitude/derating capability for outdoor/plant use.
- High efficiency (~90–92%)which reduces heat load and improves reliability.
More details & highlights
- Designed specifically for ultra-high DC inputs (250 Vdc to 1500 Vdc) and able to withstand short surge conditions (manufacturer test/surge ratings are provided in the datasheet).
- Built-in protections typically include over-current, over-voltage, thermal shutdown and input reverse/undervoltage protections (refer to datasheet for trip thresholds and behavior).
- EMC and safety: Meets relevant industrial EMC and safety standards (details and certificates are listed in the product documentation).

Types we supply — variants & differences
We supply the four RSDH-150 variants commonly requested:
- Mean Well DC-DC Converters RSDH-150-12— 12 V output, 10 A (≈120 W usable, suited for 12 V systems and control electronics).
- Mean Well DC-DC Converters RSDH-150-24— 24 V output, ~6.2 A (≈150 W, common for industrial control/relays).
- Mean Well DC-DC Converters RSDH-150-32— 32 V output, ~4.68 A (≈150 W, used where slightly higher bus voltages improve efficiency).
- Mean Well DC-DC Converters RSDH-150-48— 48 V output, ~3.12 A (≈150 W, ideal for 48 V telecom/remote power rails).
Difference between variants: identical mechanical and input characteristics; they differ only in nominal output voltage and corresponding maximum output current (power is matched ~150 W). Choose the model that matches the required output rail and current budget. contact SCB Industries — we’ll recommend the correct model and provide lead time, pricing and technical docs.
Common applications
