The Behlman PF1350 and PF1351 AC frequency power supplies from Powerstax target mission-critical industrial and military powers system designs.
The
PF1350 has three fixed, selectable output frequencies; 50 Hz, 60 Hz and
400 Hz, along with two voltage ranges; 0 to 135 VAC and 0 to 270 VAC.
These units offer up to 1350 VA of AC power from local power inputs
between 95 VAC and 270 VAC. 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 45 Hz to 500 Hz, with a 45 Hz to 1000 Hz
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 in. (88.9
mm) 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.
