TECHNICAL DATASHEET
Sync DIN Rail Power Supply
24V 30W 1 Phase (NEC Class 2) / DRS-24V30W1NZ
General Description
The ultra-compact and competitively priced Delta Sync DIN rail power supply series is designed for industrial applications requiring
highly reliable power supply within a tight space. The Sync series operates with universal AC input range and offers full power up to
55°C. The output is adjustable from 24-28 volts, and can support up to 3000 microfarads of load capacitance. A green LED indicates
output is present. All models in the series are certified according to IEC/EN/UL 60950-1 Information Technology Equipment (ITE),
IEC/EN/UL 62368-1 Audio/video, information and communication technology equipment and UL 508 Industrial Control Equipment
(ICE). The series is also fully compliant with RoHS Directive 2011/65/EU for environmental protection. NEC Class 2 and Limited Power
Source (LPS) approvals are available for this product.
