Overview
MDR-10-24 Overview
The DAPPRA MDR-10-24 (SKU: OE79) is the 24V model in the entry-level 10W MDR tier. It provides a fixed 24V DC output at 0.42A from a universal 85–264 VAC input in a 22.5 mm ultra-slim blue plastic housing. The output is factory-set with no +V ADJ potentiometer, and the unit is NEC Class 2 / LPS compliant.
It is suited to very low-power 24V loads: a few 24V sensors, signal relays or a small indicator cluster whose combined draw stays within 0.42A. The MDR-10-24 includes hiccup-mode short-circuit, overload (above 105%) and over-voltage (27.6–32.4V) protection, plus a DC OK active signal for logic-level status monitoring. Efficiency is 84%, the highest in the MDR-10 series, and ripple is 150mVp-p.

MDR-10-24 FAQ
What is the DAPPRA MDR-10-24?
The DAPPRA MDR-10-24 (SKU: OE79) is a 10W single-output industrial DIN rail power supply providing 24V DC at 0.42A from a universal 85–264VAC input, in a 22.5 mm blue plastic housing with fixed 24V output (no +V ADJ) and DC OK active signal.
Does the MDR-10-24 have a +V ADJ potentiometer?
No. The MDR-10 series has a fixed output voltage with no +V ADJ. The 24V output is factory-set with ±3.0% tolerance. If an adjustable 24V output is required, the MDR-20-24 provides a +V ADJ potentiometer with a 21.6–26.4V range.
What is the over-voltage protection threshold of the MDR-10-24?
Over-voltage protection triggers at 27.6–32.4V. The output enters hiccup mode and recovers automatically after the fault is removed.
What is the ripple and noise of the MDR-10-24?
Maximum 150mVp-p, measured at 20MHz bandwidth with a 0.1μF and 47μF parallel capacitor. This is higher than the 5V model (80mVp-p) and the 12V/15V models (120mVp-p) in the MDR-10 series.
What is the typical efficiency of the MDR-10-24?
The MDR-10-24 achieves 84% typical efficiency at 230VAC input and full load, the highest in the MDR-10 series (5V: 77%; 12V/15V: 81%).
What is the input voltage range of the MDR-10-24?
85–264VAC single phase (47–63Hz) or 120–370VDC. Do not connect to 380VAC three-phase supply.
What protection functions does the MDR-10-24 include?
Short-circuit protection, overload protection (above 105%, hiccup mode auto-recovery) and over-voltage protection (27.6–32.4V, hiccup mode auto-recovery).
Is the MDR-10-24 DIN rail mountable?
Yes, TS35/7.5 or TS35/15 DIN rail, 22.5 mm width, vertical orientation only.
What are the dimensions and weight of the MDR-10-24?
22.5 × 90 × 100 mm (W × H × D), approximately 0.17 kg.
What is the terminal pin assignment of the MDR-10-24?
TB1: Pin 1 = FG, Pin 2 = AC/N, Pin 3 = AC/L. TB2 (3 pins): Pin 1 = +V, Pin 2 = −V, Pin 3 = DC OK active signal.
Does the MDR-10-24 have a DC OK relay contact?
No. It uses a DC OK active signal (logic-level), not a relay contact. For a dry relay contact, choose MDR-40 or higher.
Can the MDR-10-24 power a small 24V solenoid valve?
A very small 24V solenoid valve can be powered if its holding current stays within 0.42A and its inrush current does not exceed the hiccup overload window. However, most industrial solenoid valves draw more than 0.42A; check the valve datasheet before connecting. For typical valves, step up to the MDR-20-24 (1A) or MDR-40-24 (1.7A).
Can the MDR-10-24 be used in a sealed enclosure?
A sealed enclosure requires thermal evaluation. The MDR-10-24 uses natural convection cooling and derates above 50°C. Ensure internal cabinet temperature stays within the derating curve.
What is the no-load power consumption of the MDR-10-24?
Below 0.75W, supporting energy-efficient standby operation.
What certifications does the MDR-10-24 have?
UL508, UL60950-1, TUV EN60950-1, EAC TP TC 004, BSMI CNS14336-1 and AS/NZS 60950.1. NEC Class 2 / LPS compliant. Confirm model coverage for your destination market.
