Product Overview
![T-60 switch power supply]()
The Leyu T-60B is a 60W triple-output switching power supply designed for industrial applications requiring three independent DC voltage rails. This compact unit delivers 5V/5A on CH1, 12V/2.5A on CH2, and -12V/0.5A on CH3 — enabling a single power source to feed multiple subsystems such as control logic, analog circuits, and peripheral drivers.
The T-60B supports universal AC input from 85V to 264V (47–63Hz) and 120V to 370VDC, making it suitable for global deployment without the need for voltage selector switches. Its chassis-mount form factor, free-air convection cooling, and comprehensive protection suite make this unit a practical solution for system integrators seeking reliable multi-rail power in a 60W footprint.
Product Features
Triple Independent Outputs
— Provides 5V (0.5~7A), 12V (0.2~3.5A), and -12V (0~1A) from a single AC input, eliminating the need for multiple separate power supplies.
Universal AC Input
— 85–264VAC (47–63Hz) and 120–370VDC input range ensures compatibility with power grids worldwide; ideal for export-oriented equipment.
Built-in Protection Circuitry
— Short circuit protection, overload protection (105%–150% trip threshold), and over-voltage protection (115%–135% hiccup mode) with auto recovery after fault removal.
Free Air Convection Cooling
— Fanless design enables silent operation, reduces mechanical failure points, and is ideal for dust-sensitive or noise-restricted environments.
LED Power-on Indicator
— Provides immediate visual confirmation that input power is present and the supply is operational.
Fixed 50KHz Switching Frequency
— Delivers consistent EMI characteristics, simplifying system-level compliance testing and filter design.

Product Advantages
Typical efficiency reaches 72% under full rated load, low power loss reduces equipment heating and prolong service life of matched electronic components; leakage current less than 3.5mA@240VAC for safer electrical use.
Overload triggers output shutdown automatically, overvoltage adopts hiccup mode; power supply restores normal output once abnormal load/voltage is removed, no need manual restart frequently to cut maintenance cost.
Fanless structure avoids fan failure and dust accumulation issue, reduce later maintenance expense and fit sealed control cabinet installation.
Every T-60B undergoes input surge test, high voltage withstand test and full-load burn-in aging before shipment; comply with EN55022,EN61000 series EMC standards, strong anti-electromagnetic interference for complex industrial wiring environment.
Standard 159×97×38mm metal casing with reserved fixed screw holes, convenient for cabinet fixed mounting, save internal cabinet layout space; bulk order customizable service available for LEYU factory direct supply

FAQ
Q1: What output voltages and currents does the T-60B provide?
The T-60B provides three outputs: CH1 at 5V DC (rated 5A, adjustable from -5% to +10%), CH2 at 12V DC (rated 2.5A), and CH3 at -12V DC (rated 0.5A). Total rated power is 61W.
Q2: What AC input voltage range does the T-60B support?
The T-60B supports universal input from 85V to 264V AC, 47–63Hz, as well as 120V to 370V DC. It works in all major countries without a voltage selector switch.
Q3: What protection features are built into the T-60B?
The T-60B includes short circuit protection (SCP), overload protection (OLP) with a 105%–150% trip threshold, and over-voltage protection (OVP) with a 115%–135% hiccup mode. All protections automatically recover when the fault condition is removed.
Q4: What is the operating temperature range?
The T-60B operates from -10°C to +60°C (20%–90% RH, non-condensing). Storage temperature range is -20°C to +85°C (10%–95% RH). Derating may be required at higher ambient temperatures.
Q5: What certifications does the T-60B hold?
The T-60B is designed to reference UL1012, UL60950, TUV EN60950 for safety, and EN55022, EN61000-3-2,-3, EN61000-4 series for EMC. It carries approvals including CB, CE, TUV, and UL.
Q6: Does the T-60B require a minimum load to regulate properly?
Yes, like many multiple-output switching power supplies, the T-60B requires a minimum load of approximately 20% on the primary output (CH1, 5V) to maintain optimal regulation and stability across all outputs.
