Please note: This transformer can only be used on servos.
Product parameters
Input voltage: three-phase four-wire (360V-415V)
Output voltage: three-phase three-wire (200V-230V)
Frequency: 50HZ/60HZ
installation steps
1. RST is connected to the three-phase 380V hot line
2. N is connected to the neutral wire. It is recommended that the diameter of the neutral wire be 1.4 times the diameter of the live wire (see Table 2.1 for the recommended specifications of the transformer input neutral wire), and the connection must be firm.
Table 2.1 Recommended specifications for transformer input neutral wire:
Power (KW) Input zero line (mm2)
2/3 / 4.5 2.5
5.5 / 7.5 4.0
11/15 6.0
20/25/30 10.0
3. No-load inspection (without servo driver): connect RSTN and power on. Use a multimeter DC meter to measure the voltage between L1 and L3. The normal voltage is 190±10V. If these two points are abnormal, do not connect to the server;
4. Turn off the power supply and connect the servo driver, transformer L1, L2, L3; otherwise, the servo driver will not work normally.
5. Where single-phase 220V power is used on the equipment (such as 220V cable system, 220V power supply
heat fan, etc.), you can use a live wire and a neutral wire to take power before the servo transformer;
6. Repeatedly check the above circuit, and turn it on after confirming that it is correct. The servo drive shows that it is ready to work.
