Safety considerations

The EHS series of converters are certified to IEC/EN/CSA/UL 60950. If this product is built into information technology

equipment, the installation must comply with the above standard.

An external input fuse (5A to 30A recommended), must be used to meet the above requirements.

The output of the converter [Vo(+)/Vo(-)] is considered to remain within SELV limits when the input to the converter

meets SELV or TNV-2 requirements.

The converters and materials meet UL 94V-0 flammability ratings.

Notes:

1. Input Reflected Ripple is specified when measured with the filter shown below

2. Output Ripple and noise is specified when measured with a 10uF electrolytic and a 1uF ceramic

capacitor at the converter output pins

3. Transient response is specified with a 470uF tantalum capacitor at the output of the converter
