SPECIFICATIONS: DIA30 SERIES

All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.

We reserve the right to change specifications based on technological advances.

At least 330uF E-Cap is suggested to be added to the input terminal to stabilize the input voltage source.

NOTES

1.  Transient recovery time is measured to within 1% error band for a step change in output load from 50% to 75%.

2.       This power module is not internally fused. We recommend protecting the converter by a slow blow fuse in the input supply line.

3.       To meet EN61000-4-4 & EN61000-4-5 an external capacitor across the input pins is required. Suggested capacitor 330µF/100v.

4.       This product is listed to applicable standards and requirements by UL.

Due to advances in technology, specifications subject to change without notice.
