Product Details

Enclosed switching power supplies have a metal or plastic case covering their internal PCB. It is installed inside the enclosure of the end system. Enclosed power supplies include 2 different sets of power supplies with fans and without fans, depending on their power rating or design philosophy.

The 350W AC-DC Switching Power Supply brings you the largest range of high-reliability, high-efficiency power supplies. From single-output power supplies to PFC functional power supplies, our range of enclosed switching power supplies provides a variety of options for your application, and our products are designed to meet the safety and efficiency requirements associated with industrial applications.

Factory

Specification:
【1】Good quality and high performance
【2】AC 110V / 220V to DC 12V
【3】Protection: short circuit, overload, overvoltage, overtemperature protection
【4】Cooling by natural air convection (not recommended for use in bathrooms)
【5】The unit can work for a long time with an underrated current and a good heat dissipation environment.
【6】The actual output current depends on the circuit load.

notes:
1. Internal high pressure, please do not remove the cover. The qualified service personnel only.
2. Select by switch before powering on, please check whether the input voltage is damaged.
3. Please do not let the equipment work for a long time under the rated current! Generally, it is better to work below 80% of the rated current.

Strong anti-interference, high efficiency, efficient heat dissipation, high pressure resistance, stable performance, built-in controllable fan, low noise, efficient heat dissipation.

Remarks ① Ripple and noise measurement method: use a 12 "twisted pair, and connect 0.1uF and 47uF capacitors in parallel at the terminal, and measure at 20MHz bandwidth. ② The efficiency is tested at an input voltage of 230VAC, rated load, and an ambient temperature of 25 ℃. Accuracy: including setting error, linear adjustment rate and load adjustment rate. Linear regulation test method: under rated load from low voltage to high voltage test load regulation test method: from 0% - 100% rated load. The start-up time is measured under the cold start state. The quick and frequent switch on and off may increase the start-up time. When the operating altitude is higher than 2000m, the operating environment temperature needs to be reduced by 5 ℃ / 1000m
