DRP 24V 2PH - Delta 2 Phase AC/DC DIN Rail

Product Overview


Delta Electronics CliQII 24Vdc 2 Phase DIN Rail Power Supplies

The CliQ II DIN rail power supply series with a new model offering two phase 2 x 180-550Vac (for L-L) or single phase 180-305Vac (for L-L) for 24V/5A abd 24V/10A outputs.  The DRP24V120W2BN and DRP24V240W2BN has safety approvals for single phase and two phase input according to IEC/EN/UL 60950-1 and UL508 safety standards.  The product features wide AC input voltage for single or two phase range.  Such feature can protect the power supply from damage when user accidentally apply two phase input on the single phase power supply connection.  The product performs under wide operating temperature form -30C to +70C with 2-Phase and 3-Phase application (for L-L) . Conformal coating is applied on the PCB assembly to protect against dust and chemical pollutatn to withstand harsh industrial environments.  Other major safety approvals included.
