The device provides a voltage-proportional-to-absolute-temperature (VPTAT) output, as well as individual under-temperature and overtemperature
alert outputs, defined by user-adjustable thresholds.
For safety, the Freedom load bank features main line circuit fusing, wrong voltage protection and overtemperature
Because older fossil-fuel plants often are operated cyclically, thermal shocks and overtemperature
excursions are created during the frequent start-ups, shutdowns, and load swings.
Coordinating overcurrent, overtemperature
and overvoltage protection can help designers minimize component count, comply with safety agency requirements and reduce warranty returns resulting from failed motors and damaged control boards.
Output overvoltage, overcurrent and overtemperature
fault protection are included in the regulator.
Protection circuitry provides overtemperature
and short-circuit protection plus voltage fold-back that maintains undistorted waveforms during overloads.
The converter has a number of protection features including overcurrent, overtemperature
, input undervoltage, and output short circuit.
Protective circuitry with fail-safe opto-isolated fault annunciation including overcurrent, overvoltage, overtemperature
, short circuit and P.
A fully programmable digital timer and an adjustable, safety overtemperature
cutout enables unattended operation for 99 hours and 59 minutes.
Additional customizable features include overspeed protection, overtemperature
and low oil pressure shutdowns, starter lockout and external shutdown input.
Additional features include standard swivel, locking casters and leveling feet; alarm contacts for remote monitoring of chamber conditions; a heated glass door that optimizes temperature uniformity; two through-wall access ports, one on the right side and one on the left side of the chamber; and an audible/visual alarm that warns of undertemperature or overtemperature
Integral protection circuitry prevents damage due to overtemperature
and load SWR conditions among the amplifier LRUs.
