AC Input
Voltage range: +/- 10% from nominal
Frequency range: +/- 5%
Single Phase models:
A1: 120VAC/1/60Hz
ABD1: 120/240/208VAC/1/60Hz
BLD1: 240/220/208VAC/1/60Hz
C1: 480VAC/1/60Hz

DC Output
DC Amps: 6 to 200 amperes
DC Volts: 24, 48 & 130VDC
DC Ouput Voltage Range - a chart is provided on the last page of the data sheet
Output Filtering (with or without a battery)
30mV RMS for single phase models
100mV RMS for three phase models
DC Voltage Regulation Steady-State
+/- 0.5% of setting from no load to full load over the specified input voltage, frequency and ambient temerature ranges
Dynamic Response (On Battery)
Maximum Voltage Transient will not exceed +/-5% of initial steady-state voltage for a step change from 20 to 100% of the full rated load. Recovery to steady-state voltage regulation does not exceed 200ms and all transient behavior disappears within 500ms.
Audible Noise
Less than 65dBA at any point 5 feet from any verical surface of the enclosure
Load Sharing
Load sharing terminal located inside of unit. When connected, identical La Marche Units are forced to share the load within +/-5% for individual unit outputs greater than 15% of the rated output.
Temperature Compensation
The TPSD can adjust the output voltage level for temperature changes. The adjustment is based off an internal sensor inside the unit or an optional sensor. Temperature compensation is done in steps of approx. -0.001V/cell/C (consult factory for other compensation rates).
Current Soft Start
The output current will gradually increase after the charger is turned on, eliminating surges and overshoot
Current Limit
The charger have an inherent magnetic current limiting feature. Electronic current limiting control circuitry provides for an adjustable value of 50 to 115% of the rated output current
AC Breaker
Single Phase UnitsA two-[p;e breaker opens both legs of the AC service to 208VAC and 240VAC. Breaker opens phase side of 120VAC service.
Three Phase UnitsA three-pole breaker opens all three legs of the AC service.
DC Breaker & DC Fuse
Standard units are equipped with a fuse or a 2-pole circuit breaker. For units equipped with a fuse, an optional breaker is available. Refer to the model chart on the data sheet for further details
overall dimensions and weights are subject to change due to innovative product development and design. When space requirements are critical, please consult factory.
Our enclosures are very versatile. Some units can be wall, floor or rack mounted and others can be wall or floor mounted. see the Case Specifications Chart on the last page of the data sheet for further details.
