1.) INPUT DATA
Nominal input voltage
24-48VDC
Voltage range
Nominal current
20A max
22-60VDC
40A max
Input voltage alarm / relay contacts
24V system:
both Vin1 & Vin2 >18V +/- 5% or
<30V max. relay contacts
48V system:
both Vin1 & Vin2 >36V +/- 5% or
<60V max. relay contacts
Note: The LED will turn on when The Vin1 & Vin2 > 18V +/- 5% (For 24V system) or > 36V +/- 5% (For 48V system) and not
more than 30V (For 24V system) or not more than 60V (For 48V system), The relay contacts will be closed. If Vin1 & Vin2 is under
or over this range, The LED will be turn off.
2.) OUTPUT DATA
Nominal output voltage UN / tolerance
Nominal current
Vin-0.65V (Typ)
20A max / 40A max
Derating above +50 °C
> 50°C (2.5% / K.)
Short circuit / Over Load Limit
(<25A for DRR- 20A)
(<50A for DRR- 40A)
Note: The overload condition must be controlled by The PSUs in parallel; The limit of input current would not more than 25A (For
20A module) or not more than 50A (For 60A module).
Efficiency
> 97% typical.
