Overview
MDR-60-48 Overview
The DAPPRA MDR-60-48 (SKU: OE92) is the 48V model in the 60W MDR tier. It provides 48V DC at 1.25A from a universal 85–264 VAC input in a 40 mm blue plastic housing. At the same 60W power level, the 48V output draws half the current of the 24V model (1.25A vs 2.5A), reducing cable voltage drop for long-distance distribution.
It is suited to 48V telecom equipment, PoE injectors and 48V industrial control loads whose combined draw stays within 1.25A. The MDR-60-48 includes a dry DC OK relay contact (30V/1A), 48–56V +V ADJ, hiccup-mode overload protection and over-voltage shutdown (57.6–64.8V). Efficiency is 87% and the unit is certified for Class I Division 2 T4 hazardous locations. Ripple is 200mVp-p, higher than lower-voltage models, so verify connected equipment tolerance.

MDR-60-48 FAQ
What is the DAPPRA MDR-60-48?
The DAPPRA MDR-60-48 (SKU: OE92) is a 60W single-output industrial DIN rail power supply providing 48V DC at 1.25A from a universal 85–264VAC input, in a 40 mm blue plastic housing with 48–56V +V ADJ, DC OK relay contact and hiccup-mode protection.
Why choose 48V instead of 24V for a 60W load?
At the same power, 48V draws half the current of 24V (1.25A vs 2.5A). Lower current reduces cable voltage drop and allows thinner conductors, which can simplify long-distance distribution. However, the connected equipment must be rated for 48V — it is not interchangeable with 24V devices.
What is the over-voltage protection threshold of the MDR-60-48?
Over-voltage protection triggers at 57.6–64.8V (120–135% of 48V). The output shuts down and requires re-powering to recover. This threshold sits above the 56V maximum adjustment point, so normal potentiometer adjustment will not trigger it.
What is the output voltage adjustment range of the MDR-60-48?
48–56V via the +V ADJ potentiometer. The 56V upper limit is 16.7% above nominal; verify that connected 48V equipment tolerates the higher voltage before turning it up. Many 48V telecom and industrial devices accept up to 60V, but check each datasheet.
What is the typical efficiency of the MDR-60-48?
The MDR-60-48 achieves 87% typical efficiency at 230VAC input and full load, the highest in the MDR-60 series alongside the 24V model (both 87%).
What is the ripple and noise of the MDR-60-48?
Maximum 200mVp-p, measured at 20MHz bandwidth with a 0.1μF and 47μF parallel capacitor. This is higher than the 12V/24V models and is typical for a 48V output in this power class. Verify that connected equipment tolerates this ripple level.
What is the input voltage range of the MDR-60-48?
85–264VAC single phase (47–63Hz) or 120–370VDC. Do not connect to 380VAC three-phase supply.
What protection functions does the MDR-60-48 include?
Short-circuit protection, overload protection (105–150%, constant-current limiting with auto-recovery) and over-voltage protection (57.6–64.8V, shutdown and re-power).
Does the MDR-60-48 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 PLC input.
Is the MDR-60-48 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-60-48?
40 × 90 × 100 mm (W × H × D), approximately 0.30 kg.
What is the terminal pin assignment of the MDR-60-48?
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-60-48 power PoE injectors or 48V telecom equipment?
The MDR-60-48 can power 48V telecom equipment or a small number of PoE injectors if their combined current stays within 1.25A. For multiple PoE ports or high-power PoE devices, calculate the total 48V load carefully — PoE injectors can draw significant inrush current at startup.
Can the MDR-60-48 be used in a hazardous location?
The MDR-60 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-60-48 have?
UL508, UL60950-1, TUV BS EN/EN60950-1, EAC TP TC 004, BSMI CNS14336-1 and AS/NZS 60950.1, plus Class I Division 2 T4 (confirm certificate coverage).
