Features

Unregulated

Converters

• 1kVDC/1s or 2KVDC/1s basic isolation

• Optional continuous short circuit protected

• UL94V-0 package material

• No heatsink required

• Efﬁciency to 85%

Description

The RN series of compact 1.25W single output converters are especially useful when more than 1W of

power is required, but there are space restrictions than make a 2W converter unsuitable. The converter

series feature an industrial ambient temperature operating range of -40°C to +85°C without derating

and up to 100°C ambient temperature with derating. Options include 1kVDC or 2kVDC isolation and

continuous short circuit protection (/P).

Model Numbering

Notes:

Note1: Efﬁciency is tested at nominal input and full load at +25°C ambient

Note2: Max Cap Load is tested at nominal input and full resistive load and is deﬁned as the

capacitive load that will allow start up in under 1s without damage to the converter

Notes:

Note3: standard part is without continuous short circuit protection

add sufﬁx „/P“ for continuous short circuit protection

Note4: add sufﬁx „/H“ for 2kVDC/1s isolation

or add sufﬁx „/HP“ for continuous short circuit protection and 2kVDC/1s Isolation

Ordering Examples:

RN-0505S/P: 5V Input Voltage, 5V Output Voltage, Single Output with continuous short circuit protection

RN-0505S/HP: 5V Input Voltage, 5V Output Voltage, Single Output with 2kVDC/1s Isolation and continuous short circuit protection
