DC/DC Regulators

At RFWEL we offer highly efficient DC switching regulators for your DC powered equipment. Direct Current (DC) power is very critical in wireless equipment operation and is preferred because of a few reasons within the communications sector. Typically batteries can generally only provide relatively low-voltage DC power thus the need for converters. The regulators can be categorized into 4 as follow:

  • Step-Down (Buck Converters)
  • Step-Up (Boost Converters)
  • Step-Up/ Step-Down (Buck or Boost Converters)
  • Negative Output

DC/AC Power Inverters

Typical wireless sites are run on DC power fed from battery banks/ backup UPS to offer a means of backup and uninterrupted operation in the absence of mains AC or solar power. Not all equipment at the wireless site will run on DC, some will be powered via AC. Need therefore arises for DC-AC inverters for different voltages.

When choosing an inverter consider the following:

  • Match inverter voltage to backup battery/ UPS output voltage
  • Determine the total power consumption of loads to be connected and ensure the watteage of your inverter exceeds this by 30%. (Peak wattage of inverter should exceed peak load wattage)
  • Wave output of the inverter (Some wireless devices are sensitive to square waves and require perfect sine waves). To achieve a perfect sine more circuitry will be needed to filter the waveform thus driving the inverter prices up.
