Unique Three-Phase to Single-Phase Converters

The ED-M Series Frequency and Phase Converter offers a unique set of capabilities in a compact and lightweight package.

The Ideal Solution to Phase Imbalance Problems

Phase imbalance occurs when single-phase equipment with various current ratings are connected to the individual phases of a three-phase source. Other three-phase equipment connected to the same power system may experience problems as a result. Phase imbalance can result in high or excessive third order harmonics, nuisance tripping of circuit breakers and destructive over-heating.

The ED-M Series solves this problem by operating from 400Hz, three-phase power, and converting it to a DC voltage. The DC voltage is then filtered and regulated and directed into the Pulse Width Modulated (PWM) inverter stage, where a new single-phase sinewave output is created.

Using this topology, current is drawn equally from all three phases, while the ED-M supplies clean, regulated single-phase power to the critical load. The ED-M’s low output impedance enables it to start up and power difficult loads with high instantaneous current demands.

The Ideal Solution to Difficult Power Problems

The patented ED Series double conversion design protects against the following power quality problems:

  • Brownouts, surges, spikes & high voltage transients
  • Generator voltage and frequency drift
  • Momentary and sustained power outages
  • Noise and harmonics

The Ideal Frequency Converter Solution

The ED-M’s output frequency can be factory configured to 50, 60 or 400Hz. The frequency can be independent of the incoming utility frequency. Due to this unique flexibility, the ED may be used in a wide range of domestic, international and military applications, where frequency conversion is required.

The Ideal On-line UPS Solution

The external battery bank is connected to the ED-M Rackmount Frequency and Phase Converter, adding on-line UPS functionality. An internal 400ma battery charger and external battery connector are standard on every unit.

This standard model ships with maintenance-free, VRLA batteries. The batteries have a 10-year rating (@20ºC) and a wide operational temperature range of -60ºC to +80ºC.

Dual RS-232 Communitactions Ports:

The unit supports concurrent RS-232 based remote monitoring via two independent RS-232 ports. The monitoring communications protocol is available from Falcon upon request.
