Description

The RPP40 series 4:1 input range DC/DC converters are ideal for high end industrial applications and COTS Military

applications where a very wide operating temperature range of -45°C to +115°C is required. Although the case size

is very compact, the converter contains a built-in EMC filter EN-55022 Class B without the need for any external

components. The RPP40 is available in a ribbed case style for active cooling. They are UL-60950-1 certified.

Features

ICE

Technology*

• +115°C Maximum Case Temperature

• -45°C Minimum Case Temperature

• Built-in EMC Filter

• Ribbed Case Style

• 2250VDC Isolation

• Wide 4:1 Input Voltage Range

• Built-in EMC Filter, EN-55022 Class B

RPP40-2412SW

* ICE Technology

ICE (Innovation in Converter Excellence)

uses state-of-the-art techniques to minimise

internal power dissipation and to increase

the internal temperature limits to extend the

ambient operating temperature range to the

maximum.
