The Moeller DF51 inverter replaces the phased-out DF5 series, VSD Variable frequency drive.
We carry a range of all models of the Moeller DF51 inverter from stock, boasting the largest stocks of Moeller inverters held outside Moeller Germany.
The DF51 has been superceded by the PowerXL DC1. We may have some stock remaining, and we can still offer qutoes for servicing and repair. Contact us for pricing and availability.
