DRR-40□
22-60Vdc
20A max
40A max
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.
Output Data
Nominal Output Voltage / Tolerance
Vin-0.65V (Typ)
Nominal Current
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.
