Ideally suited for Cycler/Battery Emulator and Measurement/Control Cabinets

Built for maximum reliability in the most demanding environments, the nVent SCHROFF Varistar modular platform ensures the highest flexibility on a single platform – more than 20,000 different configurations can be created with it simply by using standard components.

At its core, the platform features robust steel profiles, allowing the greatest range of applications. The frame meets the requirement classes up to DL6 in accordance with IEC 61587-1 and support static loads up to 1,600 kg (3,500 lbs.). The profile has built-in 25 mm grids in all three dimensions (height, width and depth,) providing a wide variety of options for mounting components and accessories. Cable eyes, for instance, can be easily affixed directly onto the frame.

  • Heavy load equipment in the rack
  • Complex cabling (Width from 600 mm)  
  • EMC, IP protection and fire safety version available

Thermal Management Solutions

thermal management, test equipment, electric vehicle testing, automated test equipment

Maintaining the optimal temperature for equipment is critical to maximizing performance. As temperatures rise, electronics – especially the power supply, DAQ and other systems that require higher heat dissipation – can overheat, causing malfunction and device failure.

Our thermal management experts can help you evaluate your application needs, and make recommendation on how to design your infrastructure solution for optimal performance.

For example, for regular rack setups, many applications benefit from a top panel with fan:

  • Raised top cover with fan unit
  • Raised Top Cover, steel 1.5 mm, powder coated
  • Assembled with 6 fans 230VAC
  • Schuko/IEC 60320 C12 plug

We offer a full portfolio of thermal management solutions, including fans, air-conditioners and heat exchangers.

Installing a fan speed control unit to control the temperature of the test equipment improves the energy efficiency of your test rack.

  • Suitable for all AC fans and fan units (up to 300 W) with IEC 60320 C13 plug (plug and play)
  • Simple adjustment of switch-on temperature (with knob and digital display)
  • External sensor can be fitted at a desired measurement point
  • Open-collector output (parametrizable)
  • Alarm output (active/passive) DC fans (PWM output)
  • Remote display (via optional digital display with front panel)
  • Speed controller; input/output voltages 115 ... 240V AC

Power and Safety Layout

PDU with emergency stop, power distribution unit

Because test systems often consist of many heterogeneous internal components that require different currents and power, and also may be deployed in different regions with different power sources, selecting the right solutions for power and safety management is critical. The nVent SCHROFF power distribution units (PDU) can be configured and adapted to meet your requirements.

PDU with EOP (emergency off panel). CE approved.

PDU without EOP

Either as 19” rack mount unit, or as regular PDU with intelligent remote option. CE and UL approved.

System Layout

PXIe, PXI express

PXI and PXIe systems consist of three main hardware components: a chassis with backplane, controller and modules. The PXIe chassis is a rugged mechanical form-factor and has integrated timing / synchronization function that is used to route synchronization clocks, and triggers internally. A variety of vendors focus on developing plug-and-play modules for the PXIe chassis and controller. All of these components are modular and exchangeable.

If you are building your own measurement boards based on PXI Express, the nVent SCHROFF portfolio includes the PXIe-compatible chassis, backplane, power supply and optional PXIe controller for your application.

Custom Varistar Rack Solution For Vehicle Test & Measurement

We worked with an American vehicle and clean energy product manufacturer to create a variety of rack options with a customized accessory package for ease of ordering.


The customer in this case study is an American vehicle and clean energy product manufacturer based in California. This customer came to nVent SCHROFF needing traditional protection for rack-mounted and non-rack mount devices for their battery charging, discharging, and thermal performance measurements.


This customer needed to be able to have capabilities to protect both rack-mounted and non-rack mounted devices as well as combinations of both. They wanted the flexibility to decide on a cabinet by cabinet basis as to what custom options they needed for their testing equipment.
