Mobile power supply UHV-410

AC/DCregulatedsingle-output

Product introduction
Dedicated portable DC power supply for field operation testing and maintenance of high-voltage circuit breakers and their operating mechanisms. Provides an isolated DC output for on-site switch operation tests to avoid using the site control DC system directly, reducing risk to site systems and enabling safe field testing.

Parameters
Input power: AC 220 V ±10%, 50 Hz
Operating temperature: -20℃ to 50℃
Operating humidity: up to 75% RH
Output voltage: DC 25–250 V, continuously adjustable
Rated output current: 15 A (continuous)
Instantaneous current capability: 20 A
Ripple coefficient: Voltage stability: Dimensions: 280 × 210 × 150 mm

Features

• Input and output are fully isolated; output DC is stable and reliable.

Precautions

• Before operating the power supply with a high-voltage switch, carefully read the user manual to understand the operating methods and precautions of the power supply.
• When using the power supply, it should be placed in a dry and well ventilated place, away from flammable and explosive materials.
• When connecting the power supply, pay attention to the positive and negative polarity and do not connect them in reverse.
• Before operating the switch, check that it is in the disconnected state.
• When operating the switch, it should be operated slowly to avoid sudden voltage or current increase or decrease.
• After using the power supply, the power should be cut off and the power cord should be unplugged.

Application

• Debugging before the new equipment is put into operation: Ensure that the newly installed high-voltage switch can reliably operate under various voltages.
• Regular preventive testing: Check whether the performance of in-service switches decreases over time and promptly detect signs of aging.
• Fault diagnosis: When the switch refuses to move or malfunctions, use an adjustable operating power supply to conduct a reproduction test to help locate the cause of the fault.
• Verification after maintenance: Ensure that switches that have undergone maintenance or replacement of components are restored to good condition.
