Bench Top Power Supplies provide frequency conversion.

Jan 30, 2014 - Targeting mission-critical industrial and military powers system, Behlman PF1350 offers 3 fixed, selectable output frequencies of 50, 60, and 400 Hz, along with 2 voltage ranges of 0–135 and 0–270 Vac. Unit provides up to 1,350 Va of AC power from local power inputs of 95–270 Vac. In addition to 100% power factor rating, power supply delivers ±0.7% load regulation and ±0.1% line regulation. Behlman PF1351 offers same performance, but with continuously variable output frequency from 45–500 Hz.

  • Variable or fixed voltage
  • Sophisticated protection functions
  • ±0.7% load regulation
  • ±0.1% line regulation
Powerstax, specialist provider of highly optimized power sources, now presents its customer base with the Behlman PF1350 and PF1351. Targeting mission-critical industrial and military powers system designs, these compact, power factor-corrected bench-top units differentiate themselves from competing AC frequency products on the market through their compelling mix of performance, flexibility and cost effectiveness.

The PF1350 has three fixed, selectable output frequencies; 50Hz, 60Hz and 400Hz, along with two voltage ranges; 0 to135VAC and 0 to 270VAC. These units offer up to 1350VA of AC power from local power inputs between 95VAC and 270VAC. In addition to their 100% power factor rating, they deliver a clean sine wave output with strong line and load regulation, plus high conversion efficiency levels (normally above 75%) and low total harmonic distortion (1.5% at full load). A unique overload protection system is incorporated, which folds back the voltage to maintain the rated output current without any waveform distortion occurring. A further protection mechanism latches the output open to safeguard the load from harm if short circuit conditions arise, while an internal temperature sensor is also incorporated to prevent heat damage.

Similar to the PF1350, the PF1351 gives engineers the same operational performance but with some additional functionality included. It features a continuously variable output frequency range from 45Hz to 500Hz, with a 45Hz to 1000Hz output frequency range version also available. These units can be controlled from their front panels or remotely using an optional RS232 or IEEE-488 interface.

Both the PF1350 and PF1351 power sources are supplied in compact 3.5” (88.9mm) profile enclosures that are easily and economically converted for rack mounting. The units are CE-marked, so they can be employed across all EU member states. An operational temperature range of 0°C to 50°C is supported.
