1.All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature. 2.Ripple & noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1μf & 47μf parallel capacitor. 3.Tolerance: includes set up tolerance, line regulation and load regulation. 4.The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. | ||||||
In industrial automation, communication devices, and electronic instruments, there is often a need for more than one DC voltage. Luyu Electronics designed the D‑60 series dual output switching power supply exactly for these applications. The series includes three models (D‑60A, D‑60B, D‑60C) covering the most common voltage combinations: 5V/12V, 5V/24V, and 15V/‑15V, with rated power ranging from 56W to 60W.
The D‑60 series is a 60W‑class, dual‑output open‑frame switching power supply. It accepts 85~264VAC wide input voltage (selectable via a switch) and delivers two independent DC outputs simultaneously. Each output has its own overload, short‑circuit, and over‑voltage protection, and the two channels do not interfere with each other.
From the very beginning, the D‑60 series was positioned as a cost‑effective industrial‑grade dual power supply – no extra frills, but every key parameter (ripple, efficiency, hold‑up time, temperature coefficient) is measured and verified. Every unit is 100% burn‑in tested at full load before leaving the factory to prevent early failures.
CNC machine auxiliary power – 5V for the control board MCU, 24V for solenoids or relays (D‑60B)
Dual‑output audio amplifier – +15V / -15V for symmetrical op‑amp supply (D‑60C)
Security surveillance system – 5V for the camera digital core, 12V for the PTZ motor (D‑60A)
Small PLC and industrial controller – Many domestic PLCs require 5V logic and 24V I/O power – a single D‑60B covers both
Lab test fixture – When a test bench needs ±12V or ±15V temporarily, the D‑60C is lighter and cheaper than a bench linear supply
Q: Is the ±6% voltage tolerance on CH2 (12V) of the D‑60A too high?
A: ±6% is the worst‑case specification across full load (0.3~3A), full input voltage (85~264VAC), and full temperature range. At 25℃, rated load (3A), and 230VAC input, the actual tolerance is usually within ±2%. If you need tighter regulation on 12V, you can increase the load on CH1 (this improves cross regulation) or add an external 12V linear regulator.
Q: Are the two outputs sharing a common ground?
A: Yes. Both outputs share the same GND terminal on the D‑60 series. If you need fully isolated outputs, please consider Luyu’s D‑120 dual‑isolated series.
Q: Does the D‑60 switch automatically between 85~132VAC and 170~264VAC?
A: No. It must be manually selected via the side switch. The factory default is the 230V position. If you use it in a 115V region without moving the switch, the power supply will still work, but maximum output power will drop by about 20%. Always check the switch position before applying power.
Q: Can the D‑60 run at 60℃ for long periods?
A: Yes, but with at least 20% derating. Specifically:
Below 50℃: full load allowed.
50℃ to 60℃: derate 2.5% per degree Celsius (so at 60℃, load should not exceed 75% of rated power).
This is due to the lifetime of the internal electrolytic capacitors. Also ensure at least 2cm of free air space around the power supply.
Q: Can I use the D‑60 to drive LED strips?
A: Yes, but note: the 24V output ripple of the D‑60B is 120mVp-p. For most LED strips this is fine (the human eye cannot detect it). However, if you are driving high‑resolution COB strips that are sensitive to flicker, we recommend adding a 470µF electrolytic capacitor in parallel with the output to further reduce ripple.
Q: Does the D‑60 have CE / UL certification?
A: Luyu designs the D‑60 with reference to UL60950 and EN60950 safety standards, and performs pre‑compliance EMC tests according to EN55022 etc. However, as a switching power supply is considered a component, final certification must be obtained together with the finished equipment. Luyu can provide test reports and a Declaration of Conformity (DoC) for your integration reference.
Note: All technical parameters are based on the Luyu D‑60 datasheet (rev. V2.3), measured at 230VAC input, rated load, 25℃ ambient, after 15 minutes warm‑up. Always refer to the official datasheet for actual use.
