  • Mobile DC power where you need it...when you need it!

    Do you have backup power situations where you need accessible and portable emergency or temporary DC power for critical facilities? Or need reliable, temporary DC power when a critical stationary battery or DC power system is required to be taken out of service for maintenance and/or testing? HM Cragg has a solution for these and many more backup power situations with our Mobile DC Power System. This is a fully customized and furnished portable backup-power unit designed, engineered and built in-house that caters to electric utility and telecommunications applications. Each DOT compliant unit is constructed to meet the unique specifications and system requirements of each customer.

    Ideal DC Power solution for:

    • Electric utilities for switchgear & control and communications, including substation and generating stations and NERC Std. PRC-005 compliance
    • Telecommunications, including central offices, remote switching offices and wireless sites

  • Plug Power’s GenSure hydrogen fuel cell solutions provide scalable, clean, cost-effective performance while offering an unparalleled degree of flexibility in addressing the space and runtime constraints of customer locations, with both indoor shelter and outdoor cabinet options.
  • The P4600 series battery charger by Primax is the evolution of their microprocessor-controlled “Thyristor” (SCR) based rectifier. Its advanced features allow communication, battery monitoring and maintenance automation at your fingertips. NERC compliance standards are facilitated. The P4600's user-friendly touchscreen display allows one to access all parameters in a visually interactive format. This optimal communication feature provides the ability to remotely and securely interact with all of the system parameters and set-up features including Primax's unique battery monitoring and maintenance capabilities.
  • With one easy to install cabinet, the Primax P600 EZ-Swap will fit most substation applications. All installation and servicing operations have been simplified using intelligent modular design. Minimum technical knowledge and experience is needed to install, operate, maintain and service the P600 EZ-Swap. High frequency technology reduces the overall size and weight up to 80% compared to traditional chargers.
  • The portable P600 Flex Power from Primax is a compact battery charger, having low ripple and THD for clean power efficient battery recharge and sensitive equipment. It’s user-friendly menu with its ergonomic and lightweight design makes it easy to carry for service calls where a temporary charger is needed. This charger can provide up to 35A at 125Vdc and 65A at 24Vdc or 48Vdc perfect for substation needs. It can also be used for permanent installations or to rehaul outdated chargers without disturbing your actual infrastructure.
  • The Primax P600 Hot Swap series delivers modular and cost-effective solutions for your DC backup systems. Packaged as a single module unit or within a complex system, the P600 meets your application’s demands. The broad range of controls and options fits virtually any DC backup specification while offering better efficiency and communication.
  • The P850i series inverters (DC to AC converters) from Primax are designed based on an insulated-gate bipolar transistors (IGBT) operating at high frequency to provide clean AC power from your existing DC bus. These 125kVA inverters are available with 125Vdc in single or three phase output. 250kVA can be provided from a 250Vdc bus. Inverters with up to 600Vdc bus are also available.
  • Flex'ion Gen 2 sets a new standard for uninterruptible power supply (UPS). Manufactured in Europe, Flex'ion Gen 2 new lithium-ion battery solution provides up to 220 kW per cabinet, boosting power performance by 40 percent compared with the first generation Flex’ion. Designed for data centers and other mission critical UPS applications such as hospitals and industrial processes, the Flex’ion Gen2 is compact, lightweight and capable of operating continuously at high temperatures. Its low-cobalt content of less than 1% and primary materials sourced from responsible suppliers under the Responsible Materials Initiative (RMI) enables a highly sustainable and environmentally friendly system. Flex’ion Gen2 li-ion battery system has passed rigorous testing under the UL 1973 and UL 9540A method. It is certified for use:
    • Without a built-in fire suppression system, placing Flex’ion at the highest level of safety
    • Without an air separation gap between cabinets, minimizing the space required and the Total Cost of Ownership (TCO) of the data center overall.
    • Other factors that reduce the TCO are the long calendar life of over 20 years, the low maintenance and the lightweight design. Li-ion batteries are six times lighter than valve-regulated lead-acid batteries (VRLA).
