Specifications:
The MDR-20 series includes models MDR-20-5, MDR-20-12, MDR-20-15, and MDR-20-24, each with different DC voltage outputs (5V, 12V, 15V, 24V) and rated currents (3A, 1.67A, 1.34A, 1A respectively). The rated power ranges from 15W to 24W. The output voltage adjustment range and ripple & noise levels vary by model, with line and load regulation maintained at ±1.0% for most models.

Input Specifications:
The input voltage range is 85 ~ 264VAC or 120 ~ 370VDC with a frequency range of 47 ~ 63Hz. Efficiency varies from 76% to 84% depending on the model. The inrush current is specified as 20A/115VAC and 40A/230VAC.

Protection Features:
Overload protection is provided with a constant current limiting feature, and overvoltage protection shuts down the output voltage, requiring a re-power to recover.

Environmental Conditions:
The operating temperature range is -20 to +70°C, with storage conditions of -40 to +85°C. The unit can withstand humidity levels of 20 ~ 90% RH non-condensing.

Safety and EMC Standards:
The power supplies comply with UL508, TUV EN60950-1, BSMI CNS14336-1, and EAC TP TC 004 standards. EMC compliance includes EN55011, EN55032, EN61204-3, and others, ensuring light industry level criteria A.

Mechanical Specifications:
The dimensions are 22.5*90*100mm (W*H*D) with a weight of 0.17Kg. The unit is designed for DIN rail installation (TS35/7.5 or TS35/15).

Additional Features:
The MDR-20 series includes a DC OK active signal feature, with specific resistance requirements for different models. The block diagram and derating curves provide guidance on installation and operational limits.
