Products description

Product features:

  • 1.The product is easy to install. And input/output terminal (2P 8mm foot/6P 4mm), which can be used with retained hole welding line.
  • 2.Fixed mounting holes in the four corners which prevent power failure due to movement/vibration. For details of fixed holes, please check the size chart of below.
  • 3.Iternational Universal input voltage: 85-264V AC or 110-370V DC.
  • 4.High efficiency, high power density, low output ripple noise and high voltage output accuracy(the voltage difference between light load and full load at the output interface of the product is within 0. 1V).
  • 5.High isolation between input and ouput
  • 6.High reliability, long life, industrial design.
  • 7.Overcurrent protection, short circuit protection and overtemperature protection (temperature limit 65 degrees), output with overvoltage protection.
  • 8.Loop abnormal protection (starting protection when DC has applied voltage or when the loop works abnormally and the voltage overvoltage reaches the output overvoltage protection point).
  • 9.The output has LC-pi filter without external large-capacity filter circuit.
  • 10.Three years of quality assurance

Remarks

1. Except for special instructions, the parameters of this specification are measured at 230VAC input, rated load and 25C.

2. Measurement of ripple and noise: Using a  12” twisted pair, and the terminal has two capacitors, 0. 1uF and 10uF in parallel. Measured at 20MHz bandwidth.

3.Accuracy: Including errors, linear adjustment rate and load adjustment rate.

4. The power supply should be regarded as part of the components in the system, and electro-magnetic compatibility related confirmation should be carried out with the terminal equipment.

5. Reduced output is required under low input voltage. Please refer to the reduction graph.

Product selection and Notes:

  • 1.Please refer to the specifications in detail for selection and use, otherwise the reliability of power supply will    not be guaranteed.
  • 2.All parameters of this specification are measured according to the internal standards of our company.
  • 3.It is suggested that the load power of the power supply should not exceed 80% of the rated power of the power  supply.
  • 4.With multi-output power supply, each output circuit    must be loaded and used at the same time according to the corresponding ratio. The maximum current of high precision voltage (5V) group of this series of products is 1A, and more than 1A will cause permanent damage to the products.
  • 5.Our company can provide customized products.
  • 6.We reserve the right to change specifications without prior notice.
