MD520 VFD

The MD520 is a high-performance universal AC drive. Induction motor and PM synchronous motor can be done by drive. it has feature of open loop V/F(Induction motor) and SVC or Close loop FVC control. It can use in both Heavy duty and Normal duty operation. It has wide operating voltage and product range:

• 3 ph 380-480 Vac: 0.4 to 500 kW
• 3 ph 200-240 Vac: 0.4 to 75 kW
• 1 ph 200-220 Vac: 0.4 to 2.2 kW

It has built-in DC reactor (400 V: 18.5 kW and above, 200 V: 11 kW and above) complying to IEC 61000-3-12. It supports Multiple communication options.
