PT-45C Triple Output Switching Power Supply - 45W 5V/15V/-15V - UL/EN62368-1 Certified for Industrial Instrumentation & Automation Control - Natural Cooling, Wide Range AC Input

【PT-45C Three-Output Switching Power Supply – 45W Industrial Grade】The PT-45C is a 45W three-output power supply designed specifically for industrial instrumentation, automation control, and mixed-signal electronic systems, providing both 5V digital power and ±15V analog power simultaneously. 【Precision Power Supply for Mixed-Signal Systems】 The PT-45C simultaneously outputs 5V/3A, +15V/1.6A, and -15V/0.3A, meeting the requirements of operational amplifier circuits, sensor signal conditioning, and data acquisition (DAQ) systems. The 5V channel’s 50mVp-p low ripple directly supports 12-bit ADC resolution without requiring additional filtering. The symmetrical ±15V bipolar power supply minimizes offset error in precision measurement equipment. 【Certified Reliability, Accelerated Time-to-Market】 Pre-certified to UL62368-1 and EN62368-1, featuring 3 kVAC isolation and Class B EMC compliance. Less than 0.75 mA leakage current and comprehensive protection (short-circuit, overload, and overvoltage with automatic recovery) meet industrial control standards—saving your end devices from costly certification cycles. 【Reliable Operation in Harsh Environments】 Wide operating temperature range from -10°C to +60°C; natural convection cooling supports full-load operation at 43.5W rated power— no fan required, eliminating noise and maintenance points. 2G vibration resistance ensures stability for mobile devices and high-vibration factory automation installations. 【Global Compatibility and Easy Integration】 Wide input range of 90–264 VAC / 127–370 VDC enables global deployment without voltage selection. Standard industrial dimensions (127 × 76 × 28 mm) and screw terminals facilitate quick panel mounting. 【Typical Applications】 Industrial instrumentation, PLC automation, DAQ data acquisition, sensor signal conditioning, audio preamplification, communication gateways, embedded controllers, and other application scenarios.

• Three-Channel Power Supply: The PT-45C simultaneously outputs 5V, +15V, and -15V, making it ideal for mixed-signal systems. It provides a 5V supply for MCUs while delivering a symmetrical ±15V bipolar power supply for operational amplifiers and sensor front-ends. This eliminates the complexity of a dual-power-supply design and saves 40% of board space.
• Low-Ripple Design, Ideal for Precision Instruments: The 5V channel features a ripple of only 50 mVp-p, ensuring clean ADC sampling. The ±15V output voltage accuracy is ±7%, with a linear regulation of ±1%—critical for applications with stringent signal integrity requirements, such as data acquisition (DAQ) and industrial control.
