Model Number: DRC-12V60W1 Unit Weight: 0.22 kg (0.49 lb) Dimensions (L x W x D): 91 x 71 x 55.6 mm (3.58 x 2.80 x 2.19 inch) General Description The DRC-12V60W1 is part of the Chrome DIN rail power supply series, which is designed for use in compact cabinets for home automations and the food and beverage industry. Deltas Chrome DIN rail power supply series offers double isolated input. This means that no Earth connection is required thus resulting in low leakage current. This product provides a universal input voltage range of 90- 264Vac, and a wide temperature range of -25C to 71C. The Chrome series is certified to safety standard according to IEC/EN/UL 60950-1, IEC/EN/UL 62368-1 and UL 508 for selected models. NEC Class 2 and Limited Power Source (LPS) approvals are also available for selected models.
