NOTES

1.

Heatsink is available for all models. To indicate heatsink option add “H” to the end of model number. Ex DCPSR2-5S1P2H

-Due to high output power of DCPSR2-24SXX heatsink is able to be operated at least 50ºC ambient temperature without derating when applied

input voltage does not exceed 30V. Other models can meet this condition without heatsink. Heatsink can be installed for higher operating ambient

temperature as well. For more information, please contact factory.

2.

For DCPSR2-12SXX and DCPSR3-24SXX the input should install an external 22µF/50V E/C only if the input will be switched electromechanically.

CAUTION: This power module is not internally fused. An input fuse must always be used.

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