1. SPECIFICATION
1.4.3 Output Pmtection:
(A) Current Limiting: DC output currenl is limited at an adjustable value from 90% to 110% of full bad,
factory set at 110% of full bad.
(C) Overvoltage Shutdown: If rectifier output voltage exceeds a preset adjustable value while the recti-
fier is delivering more than 3% of full bad current (24 amperes), the rectffier will shutdown, Refer to
Table 1.
1.4.4 Remote Voltage Stansing: Point of regulation can be extended to battery or power board.
1.45 Alarms: Afamt relay contacts are rated for 26 volts at one ampere.
(A) RECTlflER FAIL ALARM: A rectifier tail alarm is a&hated for any of the folbwfng conditions: loss
of AC input power. turning off the rectffmr efther manuaffy or automatically. excessive input current.

supplies posltfve battery to an afarm terminal, removes positive battery from an alarm terminal, and
activates the rectifier fafl alarm.
(C) HIGH VOLTAGE ALARM: A high voltage alarm is activated if output voltage increases above a pre-
set value. A high voltage alarm condkbn illuminates a red HIGH VOLTAGE ALARM fndiior. sup-
plies poskffe battery to an alarm terminal, and acthates the rectffier fail alarm. Refer to Table 1.
(D) LOW VOLTAGE ALARM: A bw Voltage alarm is actbated if output voltage decreases below a pre-
set value. A bw voltage alarm condkbn illumbates a red LOW VOLTAGE ALARM fndiitor and
