Output Specifications

Voltage set accuracy

±1 %

Output voltage adj. range

±10 % for single output models only.

Trim up via resistor over Trim and -Vout

Trim down via resistor over Trim and +Vout

(Resistor values tba, 0 Ohm=max. adjustment)

Regulation

– Input variation (Vmin – Vmax)

single output models: 0.2 % max.

dual output models: 0.5 % max.

– Load variation

single output models: 0.5 % max. (0 – 100 % load)

dual output models: 1.0 % max. (8 – 100 % balanced load)

Minimum load

single output models: not required

dual output models: 8 % of rated max current (operation at lower

load condition will not damage the converters.
