### 功能详解
- OUTPUT:
- Transient response: Output voltage returns to within 1% in less than 2.5 mS for a 50% load change. Peak transient does not exceed 5%.
- Overshoot: Turn-on and turn-off overshoot shall not exceed 5% over nominal voltage.
- Efficiency: Measured at 230 V and full load is 75%.
- Turn on delay: At 120 VAC is 1 second.
- Hold up time: At 120 VAC and 80% of rated maximim load is 20 ms.
- Adjustability: Adjustable with built-in trim pot, +/-5%.
- LED display: When green (LED1) is on the power supply is operating normally.
- Power good: Designated as PG on the CN1. This signal goes TTL high 100-500 mS after the output reaches regulation. It goes low at least 1 mS before loss of regulation.
- Fan drive: 12 VDC/400mA for external fan.
