8. Other hardware: variable-speed silent fan; Remote On/Off, Remote Sense, Power Good signal

Functions & Features

1. AC to DC conversion: converts mains power into stable high-power 12V DC, with an extra 5V standby rail. Total standby power consumption <0.6W @230Vac.

2. Remote Sense: compensates voltage drop on output cables to guarantee voltage accuracy at the load side.

3. Remote On/Off: allows system host controller to enable/disable power supply for convenient system power management.

4. Power Good signal: asserts once output voltage stabilizes, for MCU power-up sequence control.

5. Adaptive variable-speed fan: adjusts rotation speed based on load and temperature, low noise at 30~42dBA to reduce cooling noise.

6. Comprehensive multi-level protection: automatic latch-off for short circuit, over-current, over-voltage and over-temperature to protect equipment and patient safety.

7. Medical-grade isolation insulation and low leakage current, complying with medical device safety standards and simplifying end-product certification.

Applications

- Medical devices (BF class): dental equipment, patient monitors, rehabilitation devices, medical analyzers, diagnostic instruments

- Test & measurement instruments: laboratory test equipment, industrial inspection equipment

- Broadcast / Professional A/V: professional cameras, broadcast equipment

- Industrial automation: high-power industrial equipment, power supply for robots

- High-power LED lighting, special-purpose equipment

Selling Points

2×MOPP medical isolation, BF class, 1000W peak short-time overload capability, high power density, built-in 5V standby and PG signal. Compared with general industrial power supplies, its core advantages are medical safety certification and low leakage current, which greatly ease the medical registration process of end products.
