NOTES

1.

Chassis Mount, DIN Rail Mount, and Heatsink are available options for this series. To indicate chassis mount, add “C” to model number. To

indicate DIN Rail Mount, add “DN” to model number. To indicate Heatsink, add “H” to model number.

2.

Due to input reverse polarity protection function, chassis mount & DIN rail mount models minimum value input voltage range and starting voltage

is higher than 1VDC DIP package.

3.

Efficiency is measured in nominal input voltage and rated output load. Due to input reverse polarity protection, minimum efficiency of chassis

mount and DIN rail mount models greater than min. -2 is qualified.

4.

The capacitive loads of positive and negative outputs are identical. Maximum capacitive load offered were tested at input voltage range and full

load.

5.

This is the absolute maximum rating the converter can operate at without damage, but it isn’t recommended.

6.

The voltage of Ctrl pin is relative to input pin GND.

7.

When testing from 0%-100% load working conditions, load regulation index of ±5%.

8.

Ripple & Noise are measured by “parallel cable” method. See application notes for specific operation.

9.

This series of products using reduced frequency technology, the switching frequency is test value of full load. When the load is reduced to below

50%, the switching frequency decreases with decreasing load.

10. See EMC solution-recommended circuit for recommended circuit.

11. Customization is available.

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