Notes
1. Unless otherwise specified, all specifications are measured at an input of 220Vac, rated negative, and an ambient temperature of 25°C.
2. Ripple and noise measurement method: Use a 12 twisted pair cable with terminals connected in parallel with 0.1UF and 47uF capacitors, and measure ripple at a bandwidth of 20MHz.
3. Pressure accuracy includes setting error, linear adjustment word, and negative adjustment rate.
4. Linear adjustment rate measurement method: Test from low to high input voltage under a certain load.
5. Load adjustment rate test method: From 0 to 100% rated load.
6. Startup time is measured from a cold start state; rapid, frequent shutdowns may extend startup time.
