DCR022504 isolation specification

Clay:

1. DCR022405P devices have a UL approval for 1 second isolation test during the manufacturing process of 1kV. The external continuous voltage difference limits are defined as voltages as measured between VIN (-) and Vout (-) ground). The converter is designed as ground fault isolation device. It is not designed to operate with a continuous voltage isolation barrier at greater than 60VDC. The isolation 1 second test validates only the magnetic coating separation between primary and secondary transformer wire.

The maximum potential difference ( Vin(+) to Vout ground ) as referenced to  a common ground is limited to continuous 60V DC or 42V Peak  AC transient between Vin(-) and Output ( ground) . . The primary and secondary transformer wires will  contact each other separated by magnet wire over-coating. The transformer wires are single coating material and not dual coated. The UL listing, E199929, voltage limits are SELV or 60VDC continuous or 42V transient peak.

2. The thermal  (Ja)Junction to air temperature is 59°C/W and Jc = 24°C/W

3. The design has been frozen on 2W isolated converters.

Clay:

The design is frozen means there  are no plans to  release any new versions of the older design 2W DCR022405 series. These devices are active .

The average usage per year has been relatively constant. .No issue with production or processes.
