Loads

COM-TECH Dry Loads are available either as standalone products (Dry Loads with Heat Sinks), or as components to be integrated for OEM applications (Dry Loads for Integration and Dry Loads for Integration with Liquid Cooling). All Dry Loads can be optionally equipped with a Thermal Switch, and additionally, medium- and high-power Loads respectively with a Monitor Probe and an Integrated Directional Coupler.
COM-TECH also offers standalone high-power Oil/Water Power Loads.
All COM-TECH Loads are BeO-free, and thanks to their proven reliability, they are backed by a 10-Year Warranty.

Product Range

Dry Loads with Heat Sink
Standalone loads with integrated or added heat sink. Available for a wide range of power levels. Must be installed with fins in vertical position and unobstructed airflow.

Dry Loads for Integration
Load module for customer integration with a heat sink or liquid-cooled cold plate. Available for medium and high power levels. Special thermal paste available upon request.

Dry Loads for Integration with Liquid Cooling
Load module with a fluid-dynamic-optimized internal liquid cooling circuit, for customer integration with an external liquid cooling system. Compatible with most NTP threads and coolant liquids. Available for high power levels.

Oil/Water Power Loads
Available for high power levels with various cooling techniques:

  • Oil (static): Oil with an integrated heat sink (not requiring external power supply)
  • Oil (static) + Air: Oil with an integrated heat sink, cooled by forced air
  • Oil + Air: Closed-circuit oil circulation, cooled by forced air
  • Water + Air: Closed-circuit water circulation, cooled by forced air

Features

BeO-Free
COM-TECH Loads are completely free of Beryllium Oxide, in compliance with directive 2003/36/EC, which classifies BeO as carcinogenic. Instead, Aluminum Nitride (AlN), a non-toxic, environmentally friendly material, is used.

10-Year Warranty
COM-TECH products are renowned for reliability. All passive products are guaranteed for 10 years, while active products (e.g., forced air cooling) and resale items are guaranteed for 2 years.[/glossary_exclude

Options

Combiners

Thermal Switch
COM-TECH Dry Loads can optionally be equipped with a normally-closed thermal switch. This add-on option, available for all models, can be conveniently installed at a later stage.

Monitor Probe
COM-TECH Dry Loads can optionally be equipped with a capacitive, non-directive SMA monitor probe, providing a reference signal. This add-on option, available for medium-power models, can be conveniently installed at a later stage.

Integrated Directional Coupler
COM-TECH Dry Loads can optionally be equipped with an integrated directional coupler featuring one SMA or N female probe. This add-on option, available for high-power models, can be conveniently installed at a later stage.

Coding

COM-TECH Loads use mnemonic codes, based on Product Series, Resistor Chip Power, Cooling, Operating Band:

Eg. DT300LC:

  • DT: Product Series (DL, DH, DT…)
  • 300: Resitor Chip Power (3000 W)
  • L: Cooling, if applicable (H=Heat Sink, L=Liquid Cooling)
  • C: Max Operating Band (UHF)

DT300LC: DT Series, 3 kW, Liquid Cooled, UHF
