Overview
MDR-40-12 Overview
The DAPPRA MDR-40-12 (SKU: OE85) is the 12V model in the 40W MDR tier. It provides 12V DC at 3.33A — 40W — from a universal 85–264 VAC input in a 40 mm blue plastic housing. It sits between the 22.5 mm MDR-20-12 (1.67A) and the 60W MDR-60-12 (5A), offering 3.33A in the same 40 mm width as the 60W model.
It is suited to 12V PLCs, relay banks and sensor groups whose combined draw exceeds 1.67A but stays within 3.33A. The MDR-40-12 includes a dry DC OK relay contact (30V/1A), 12–15V +V ADJ, hiccup-mode overload protection and over-voltage shutdown (13.8–16.2V). Efficiency is 86%, ripple is 120mVp-p, and the unit is certified for Class I Division 2 T4 hazardous locations.

MDR-40-12 FAQ
What is the DAPPRA MDR-40-12?
The DAPPRA MDR-40-12 (SKU: OE85) is a 40W single-output industrial DIN rail power supply providing 12V DC at 3.33A from a universal 85–264VAC input, in a 40 mm blue plastic housing with 12–15V +V ADJ, DC OK relay contact and Class I Div 2 T4 certification.
How does the MDR-40-12 differ from the MDR-60-12?
Both use a 40 mm housing and 12V output, but the MDR-40-12 provides 3.33A (40W) while the MDR-60-12 provides 5A (60W). The MDR-40-12 is the lighter option when the load stays under 3.33A; the MDR-60-12 is needed when the load exceeds 3.33A but remains within 5A.
What is the over-voltage protection threshold of the MDR-40-12?
Over-voltage protection triggers at 13.8–16.2V (115–135% of 12V). The output shuts down and requires re-powering to recover. This threshold sits above the 15V maximum adjustment point, so normal potentiometer adjustment will not trigger it.
What is the output voltage adjustment range of the MDR-40-12?
12–15V via the front-panel +V ADJ potentiometer. The 15V upper limit is 25% above nominal; verify that every connected 12V device tolerates the higher voltage before turning it up. Most industrial 12V devices accept 13.8–14.4V, but the exact limit must be checked.
What is the typical efficiency of the MDR-40-12?
The MDR-40-12 achieves 86% typical efficiency at 230VAC input and full load, second only to the 24V and 48V models (both 88%) in the MDR-40 series.
What is the ripple and noise of the MDR-40-12?
Maximum 120mVp-p, measured at 20MHz bandwidth with a 0.1μF and 47μF parallel capacitor.
What is the input voltage range of the MDR-40-12?
85–264VAC single phase (47–63Hz) or 120–370VDC. Do not connect to 380VAC three-phase supply.
What protection functions does the MDR-40-12 include?
Short-circuit protection, overload protection (105–150%, constant-current limiting with auto-recovery) and over-voltage protection (13.8–16.2V, shutdown and re-power).
Does the MDR-40-12 have a DC OK relay contact?
Yes. TB2 pins 5 and 6 provide a dry DC OK relay contact rated 30V/1A resistive, suitable for direct PLC input.
Is the MDR-40-12 DIN rail mountable?
Yes, TS35/7.5 or TS35/15 DIN rail, 40 mm width, vertical orientation only.
What are the dimensions and weight of the MDR-40-12?
40 × 90 × 100 mm (W × H × D), approximately 0.28 kg.
What is the terminal pin assignment of the MDR-40-12?
TB1: Pin 1 = FG, Pin 2 = AC/N, Pin 3 = AC/L. TB2 (6 pins): Pins 1,2 = +V; Pins 3,4 = −V; Pins 5,6 = DC OK relay contact.
Can the MDR-40-12 power a 12V PLC and a small relay bank simultaneously?
Yes, if the PLC and relay bank's combined steady-state current stays within 3.33A. Relay pull-in current can be higher than holding current, so add the worst-case relay load to the PLC draw and verify the total before connecting. If the combined load approaches 3.33A, step up to the MDR-60-12 (5A) for headroom.
Can the MDR-40-12 be used in a hazardous location?
The MDR-40 series is certified for Class I, Division 2 T4 hazardous locations. Confirm the certificate and model coverage for your specific site classification before installation.
What certifications does the MDR-40-12 have?
UL508, UL62368-1, TUV BS EN/EN62368-1, EAC TP TC 004, BSMI CNS14336-1 and AS/NZS 60950.1, plus Class I Division 2 T4. Confirm certificate coverage for your destination market.
