Behlman's
BL1350 AC Power Supply / Frequency Converter / Inverter, requires
just 3.5" of rack
height,
and weighs just 40 pounds, yet it delivers 1350 VA of quality
AC power. In the BL 1350, you'll find the quality features you
expect from Behlman, fully adjustable frequency and voltage,
total harmonic distortion of less then 0.5%, high efficiency,
plus excellent line and load regulation.
There's
also a unique overload protection system that folds back the
voltage to maintain maximum rated current without output wave
form distortion and analog remote control. For rack mounted
or bench top power, no AC source combines small size, high efficiency
and low cost like the Behlman BL Series.
Features
-
1350VA in a
3.5" chassis under 45 pounds
-
Parallelable
for additional power or for 3 phase output
-
Unique overload
protection prevents output distortion
-
Remote DC programming
for voltage and frequency
-
True RMS readout
of voltage and current
-
Low cost without
compromising features or performance

Note:1:
Available
models with motor testing option add -MT (See below).
Contact
factory for additional options.
Please note that
Option MT includes all of the specifications of the standard
BL Series plus the following to features to meet the requirements
for motor testing:
-
"Soft
Start" allows starting motors in "locked rotor"
condition by folding back the voltage and slowly increasing
it as the motor starts to accelerate.
-
Capable of
starting motors which normally require 140Amps locked
rotor starting currents.
-
Capable of
supplying a running current up to 14 Amps at 50% duty
cycle.
