Input voltage range

Output voltage range

F type :-60%~+20%(2V,3V type±20%),S type ±10%
(By TRM terminal and external resistor)
Output voltage range is different according to input voltage.

Parallel operation

F type : N + 1 redandant operation. Output current balancing (PC terminal)

line regulation

0.4%,within nominal input voltage range at constant load (3.3V output : 40mV)

Load regulation

0.8%.no load to full load at constant input voltage (3.3V output : 40mV)

Cooling

Conduction cooling
(Heatsink & airflow has to chosen according to instruction manual)

Operating ambient temperature

Baseplate temperature : -20~+85°C
(output derating is different according to condition)
Ambient temperature : above -20°C

Withstand voltage

Safty standard

Approved UL1950,CSA950 and EN60950
