Overview: WYK-H series DC power supplies are easy special suspension of the use of international advanced technology developed by superposition of isolation, the product has the regulator, steady flow characteristics. Superposition function can be achieved in series or parallel voltage output and other special purpose extended up to eight simultaneous output DC power supply, the circuit structure after long-term use user test, reliable, majority of users as "national best quality." Features: 1. High frequency isolation structure; 2. High-power linear regulator technology, so that the output voltage ripple interference small; 3. Unique cooling duct technology, the cooling effect is very good, the whole volume and weight for each Species application environment; 4. with overvoltage and overload protection, the use of the operation is very simple; 5. The series DC stabilized power supply for the series-adjusted, pre-pre-stabilized high-frequency switching, power transistor level after adjustment, the province to bulky frequency transformer, the series power supply compared to traditional power source 6, with a small size, light weight, high efficiency; 7. The series of power protection function, overvoltage, overcurrent point can be continuously provided; 8. Input voltage: 220V ± 10%, 50 ± 2Hz. 9. Output voltage: 0 ~ rating. 10. Output Current: 0 ~ rating. 11. Voltage Regulation: ≤5 × 10-3 + 10mV. 12. The current adjustment rate: ≤5 × 10-3 + 15mV. 13. ripple voltage: VP-P≤100mV 14. Display: 5 × 10-3 ± word.
