Main technique parameter
.Input a voltage extent:The 80-240 VACs or 160-260 VACs
.Input frequency:45-65Hz
.Output voltage stability:≤ 0.5%
.Load stability:
1.Single road output:≤ 0.5%
2.Many road outputs:The lord controls ≤ 1%;Vice- control ≤ 5%
.The ripple and noise be worth:
1.Single road output:The 50 mVs of Vpp ≤ (0.5% output voltages absolutely are worth)
2.Many road outputs:The lord controls the 50 mVs of Vpp ≤ ;Vice- control the Vpp ≤ ,1% output voltages absolutely are worth
.Efficiency:≥ 80%
.Protect a function:
1.The overburden protect:120%-150%
2.Conduct electricity to press a protection:130%;
3.Short - circuit protection:The power supply interrupteds a work, the output voltage nears to a 0 Vs, after expeling the short circuit guarantee can recover normal.
4.The overheating protect:Adopt the switch integrated circuit, IC IC, the thermal protection.Reset:1 connect AC after minute.
.Operating temperature:0-+45 ℃s.
.Insulation strength:
Plastics box:AC3KV 10mA(I/P-O/P)
Metal box:AC1.The 5 KVs 5 mAs(I/P-O/P, I/P-FG)/AC0.The 5 KVs 5 mAs(O/P-FG)
