Operation warning
Single-phase static frequency converter-transformer rectifier
Single-phase AC power supply and rated frequency
Can be used in environments with high risk of electric shock
IP Degree of protection, such as IP23S.
U
1
Rated AC input voltage (tolerance ±15%)
I
1max
Rated maximum input current
I
1eff
Maximum effective input current
X Duty cycle - the ratio of given duration time/full-cycle time
Note 1: This ratio is between 0-1, and can be indicated by percentage.
Note 2: In this standard, the full-cycle time is 10 min.
For example, if the duty cycle is 60%, the load application time is 6 min and the subsequent
no-load time is 4 min.
U
0
No-load voltage, open circuit voltage of secondary winding
U
2
Load voltage
H Insulation class
Do not dispose electric waste with other ordinary waste.
Please take care of our environment.
