Battery Chargers

The La Marche TPSD2 Battery Charger Series is designed to perform as a Power Supply / Battery Eliminator. This model incorporates Controlled Ferroresonant technology to provide the DC system with a dependable battery charger. Updated LCD display with digital control is now standard with the TPSD2 Charger Series. The User-friendly interface makes installation even easier as all configurations are done through the display. The design of the TPSD2 utilizes special magnetics that optimizes the performance of the charger. It’s known for its High Efficiency, High Power Factor, Low Harmonic Distortion and inherent Current Limiting. The MTBF (Mean Time Between Failure) for this design is conservatively rated at 225,000 hours at 50 C°, assuring longevity and a higher return for your dollar.

La Marche I31 is an Industrial Inverter based on sinusoidal pulse width modulation (SPWM) using fully digital DSP+ IGBT technology. Inverter interface features includes a user-friendly touch-screen mimic panel for displaying power flow, voltages, currents, alarm statuses, data logging, and password-protected configuration capabilities. The I31 has a range of selectable features such as kVA rating, input/output voltages, enclosure protection ratings, isolation bypass transformers, distribution, and more. The built-in Static Switch uses power SCR’s to provide instantaneous transfer to an alternate source in less than 4ms if any disturbance occurs at the I31 output. The I31 is highly reliable and is the preferred choice for mission-critical applications, including telecommunications, emergency lighting, offshore oil exploration, utility substations, security alarms, and more.

The La Marche Model A36D Controlled Ferroresonant Rectifier/ Power Supply has many inherent advantages such as voltage regulation, high efficiency, high power factor and short circuit protection. These chargers provide adjustable voltage levels for floating or equalizing lead or nickel-cadmium cells, which can be done digitally through the LCD display. The equalize cycle is activated either manually through a switch on the front panel, or automatically scheduled. (adjustable through the menu). Steady state output voltage remains within ±0.5% of the setting from no load to full load and for AC input voltages within ±10% of the nominal input voltage. The model A36D is internally filtered to be no greater than 32dBrn (“C” message weighting) and 30 millivolts RMS for all conditions on input voltage and output load with or without batteries connected. This allows the A36D to be used as a battery eliminator.

The La Marche A31 Inverter is designed based on robust ferro technology. This DC-AC pure sine wave inverter utilizes IGBT Switching to assure reliable performance. The 22U Series provides a wide range of features such as static transfer switch and a 4-line LCD display for monitoring. It incorporates a DC input breaker and an automatic under/over voltage shutdown circuit to protect the inverter and battery. The A31 has a polarity indicator to tell you if the battery is connected incorrectly. The La Marche A31 is equipped with an input filter pre-charge circuit which includes an indicator to inform you that the inverter is ready for operation. Applications may include data centers, fire alarms, telecommunications, emergency lighting, security, oil exploration and utility substation systems.

IQ2 is an SCR-type industrial/utility charger that powers DC equipment, charges your battery, automatically tests battery performance, and communicates DC system status. IQ2 is an update of SENS’ popular EnerGenius IQ charger.

IQ2 is fit, form and function compatible with the original EnerGenius IQ. Employing the same power train as the original EnerGenius IQ, IQ2 adds the advanced DSP-based control and firmware proven in thousands of SENS’ MicroGenius and EnerGenius DC platforms.

First generation EnerGenius IQ chargers can be easily upgraded to full IQ2 function by swapping circuit boards and the front door mimic panel/LED overlay.

Demonstrating SENS’ commitment to quality and to surviving harsh industrial and utility environments, IQ2 is equipped with SENS’ unique corrosion-proof all stainless-steel housing and backed by industry-best five-year warranty.
