The OL500 series units are adjustable through manually set digital dials, or via a 25 pin
D-connector for remote operation. All other models feature toggle switches. Units have binary configured power resistors
in parallel with 16 BIT resolution or 12 STEP resolution for the OL20 and OL50 series. Most units come standard with DC
meters, optional AC meters (50/60Hz) available as a special order. Utilizing the switched meter bypass, the loads are
capable of both DC&AC (DC-1KHz) and complex waveforms (any form factor). OL100 to OL500 series models feature over-load
protection, temperature alarm, and voltage/current monitors. The floating inputs allows for application flexibility and ease
of parallel and/or series operation of many loads. OL20 to OL100 series loads operate with AC power and are meterless. Standard
load accuracy is +/-5%. |
