Audited Supplier | LVLP Series Linear DC Power Supply | |||||
|
|
||||
| Overview | |||||
| 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. |
