40-120W 85 - 900VAC Input Voltage Power Supply PVAxx-27Bxx Series for Coal Mines Applications

Mornsun released a new high voltage input dc dc converter PVAxx-27Bxx series which is specialized for the electrical equipment in coal mining. The new series PVAxx-27Bxx covers output powers of 40W, 70W, 120W now.

High voltage input dc dc converter PVAxx-27Bxx series has an ultra-wide and ultra-high input voltage range of 85-900 VAC, which meets the requirements of voltage fluctuations such as 127/220/380/660VAC in coal mining. The dimensions of the high voltage input dc dc converter PVA40-27Bxx series(138*82*32mm) and PVA70-27Bxx series (155*95*41mm) are smaller than the traditional solution of industrial frequency transformer with AC/DC power supplies. Besides, they only have one input port and don't need to change the wire, which can completely avoid the risk of a wrong connection and save the cost of customers’application.

In addition, the PVAxx-27Bxx series has an isolation voltage of 4000VAC and an industrial operating temperature range of -40℃ to +70℃, and its EMS EFT/Surge is ±4KV. Protections of output short circuit, over-current, and over-voltage are included.
