Main technique parameter:
· Input voltage extent:The 160-260 VAC
· Input frequency:45Hz-65Hz
· Output voltage stability:≤ 0.5%
· Efficiency ≥ 78%
· Load stability:
1.Single road output:≤ 0.5%2.Many road outputs:The lord controls ≤ 1%;vice- control ≤ 5%
· Ripple and noise be worth:
1.Single road output:The 50 mVs of Vp-p ≤ (1% output voltages absolutely are worth)
2.Many road outputs:The lord controls the 50 mVs of Vp-p ≤ ;the vice- Vp-p ≤ 1% output voltages absolutely are worth
· Protection function:
a.The overburden protect:150% －s 200%; b.Conduct electricity to press a protection:130%;(choose to use)
c.Short - circuit protection:The power supply interrupteds a work, the output voltage nears to a 0 Vs, expel the empress of the shorted fault can recover normal.
d.The overheating protect:The 50 Ws adopts the switch integrated circuit, IC IC as follows, the overheating protection.Reset:1 connect AC after minute.The 100 Ws chooses to use a thermal relay above,(95 ℃s) the pass off.
· Operating temperature:-10 ℃－s+45 ℃s, 45 ℃s increase 5 ℃s each time above, the output descends 10%.
· Insulation strength:AC1.5KV5mA(I/P-0/P,I/P-FG) AC0.5KV5mA(0/P-FG)
The
· Mean time to failure, MTTF 50,000 hours
· Protects to fix for a year
