Maximum aititude

2000m

When the altitude is above 2000m to below 5000m, it is necessary to consider the use of a reduced amount.

(for each increase of 1000m, the voltage and current will be reduced by 10%)

Life expectancy

100000h(Un; Θhotspot≤55°C)

Reference standard

IEC 61071 ;IEC 60831;

Feature

1. Metal case package, Sealed with resin;
2. High voltage power system application;
3. High power circuit;
4. Resistance to high voltage, with self-healing;
5. High ripple current, high dv / dt withstand capability.

Function

In the output filter of a DC power supply, the job of the capacitor is to maintain a constant DC value by removing as much power ripple as possible.

All AC-DC converters, whether they are linear supplies or have some kind of switching element to them, require a mechanism to take the varying power on the AC side and produce a constant power on the DC side.
