DLS-48-20 Power Converter
  108-132 VAC

  50-60 Hz

  48 VDC

  20 Amps

The DLS-48-20 Power Converter from IOTA Engineering converts nominal 108-132 AC voltage to 48V DC for DC load operation.

As a power supply, the unit's tightly controlled regulation allows the user to operate a nominal 48VDC load up to 20 amps.

For 48V battery charging, use the DLS-54-13.
