LVLP - 0400- 0001S
LVLP series is linear DC power supply uses power frequency transformer AC/DC conversion technology and matured filtering circuit to ensure pure and & stable DC output
As it uses power frequency transformer, it does not have high frequency radiation interference like switching mode power supply has, so it is suitable for some special conditions that sensitive to EMC. And by its matured and perfect filtering circuit, it has super low ripple and very good output precision; also it has complete protection functions
As features above, this series is mostly used for capacitor, relay and resistor burn-in test and other kinds of test that needs high precision & low ripple DC output.
1. Over 500 models, output voltage: 0 ~ 800V, output current: 0 ~ 500A, output power: 0KW-400kW
2. Constant voltage mode and constant current mode, automatic switchable, output voltage / current continuously adjustable from 0 to rated value.
3. Over voltage protection: Over voltage value continuously adjustable from 0 to 110% rated value, auto-shut down when output voltage exceeds the over voltage set point
4. Short protection: Withstand short-circuit under start-up or any working modes, sound & light alarm when output has short.
5. Over load protection: Auto-tripping when power supply or load has fault and output current exceeds 1.5 times of rated value.
6. Current-limit protection: User set current-limit value, output current will be limited at current-limit value when load has fault.
7. Short alarm: sound & light alarm when output voltage lower than 1% of rated value and current higher 110% of rated value. (optional)
8. Automatic off-load and discharging: when power supply shutdown, power supply will automatically cut off load and discharge electric in load for safety. (optional)
