  • LmPower MODULAR RECTIFIER -48V DC Power System
    The LmPower Series is a compact -48V DC power system with high-performance rectifiers. The pre-configured LmPower models are: LMP-100A (1RU), LMP-200A (5RU) and LMP-400A (6RU). LmPower series can be mounted on standard 19” and 23” racks....

  •  The LmPower Series utilizes hot swappable high efficiency LmPower R50 1RU 3000W (50A) rectifiers at 96% efficiency. The LmPower Series offers a robust system controller with an embedded I/O interface equipped with digital inputs, dry contact alarm outputs and temperature sensors input ports. In addition, the system offers intelligent battery management, remote access, and a rectifier hibernation/cycling function for increased efficiency.

    The La Marche Industrial Uninterrupted Power System (IUPS) is designed based on pulse with modulation (SPWM) rectifier and inverter using fully digital DSP+ IGBT technology....

  • This transformer-based double-conversion IUPS is highly robust, well-proven and provides the highest level of availability. This transformer-based IUPS incorporates the latest designs and operates at high efficiency while providing galvanic isolation. The 12-pulse rectifier section generates very low total harmonic current distortion (THD) under 5% improving input power factor. The low AC ripple currents and voltage along with battery test feature improves battery life and availability. The IUPS is designed with an output transformer, allowing flexibility where bypass voltage and rectifier input voltage can be from a separate source.

    The built-in Static Switch using power SCRs provide instantaneous (less than4ms) to an alternate source if any disturbance occurs at the UPS output. The highly reliable IUPS is the preferred choice in mission-critical applications and high-power data centers compared to transformer-free UPS. The La Marche IUPS is equipped with Touch-Screen dynamic real-time mimic panel displaying power flow, voltages and currents, alarms and status, data logging, and user-friendly password protected configuration capabilities. The IUPS is highly customizable; kVA rating, Input/Output Voltages, Charger Sizing, enclosure protection ratings, distribution, isolation bypass transformer, distribution, and many more.

    The La Marche Model A77 Series Battery Charger is engineered for the demanding requirements of Switchgear, Process Control, Oil Exploration and other stationary DC power applications....

  • The A77 can automate NERC PRC-005 & TPL-001 Compliance. Powered by Microprocessor Controlled SCR technology, the A77 Series Battery Charger / Battery Eliminator has ±0.25% DC voltage regulation from no load to full load over the specified input voltage, frequency and ambient temperature ranges. These chargers are available in DC output voltages of 24, 48, 130, and 260 VDC with DC output currents from 6 amps and above. Consult factory for any special input and output requirements not mentioned above. The La Marche A77 charger provides value added features such as AC/DC breakers, easy to read LCD display with text readout alarm LED’s and form “C” alarm contacts. Communication options are available to remotely monitor and control the charger using DNP3, Modbus, IEC 61850 and SNMP protocols. The SNMP option features easier and faster charger setup and configuration using a web browser. Designed to meet IEEE-2405 & NEMA PE5, and listed to UL 1012.
