**DDRH-240 series** 

240W High Reliable 250~1500Vdc Ultra Wide Input  DIN Rail Type DC-DC Converter 

## **DC OK Relay Contact** 

|Contact Close|PSU turns ON / DC OK.|
|---|---|
|Contact Open|PSU turns OFF / DC Fail.|
|Contact Ratings (max.)|30V/1A resistive load.|



## **Function Manual** 

## **1. Current sharing** 

- (1) Parallel operation is available by connecting the units shown as below (P+,P- are connected mutually in parallel) . 

- (2) The voltage difference among each output should be minimized that less than 0.2V is required. 

- (3) The total output current must not exceed the value determined by the following equation (Output current at parallel operation) =(The rated current per unit) x (Number of unit) x 0.9. 

- (4) In parallel operation 4 units is the maximum, please consult the manufacture for other applications. 

- (5) When in parallel operation, the minimum output load should be greater than 3% of total output load. 

   - (Min. load > 3% rated current per unit x number of unit) 

- (6) In parallel operation,after overload or short circuit fault occurs, re-power on to recover.

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
