Polarity, Inc. designs and fabricates high power products including industrial high voltage power supplies, solid state RF amplifiers, ultra low noise TWT, CFA, and Klystron microwave amplifier systems, high voltage solid state modulators, ultra low noise high voltage power supplies, and noise immune custom monitor and control systems.

Polarity's mission is to develop low cost high power equipment with the highest reliability ratings in the industry. Polarity's products are put through extensive testing and quality assurance to provide the highest product value.


 

 

Polarity, Inc. has completed its second generation TWT test set that has a 15KV cathode power supply, 3ea-3KW collector power supplies that are referenced to cathode, 3KV swing grid modulator (-2500V to +500V - pulse top is relative to bias), and a 8V, 8A DC heater supply. This product was developed as a low cost solution for the TWT manufacturing industry. This TWT test machine can also be interface with Polarity's GM303-100 for a dual grid modulator test station. The test set can also be equipped with a 3500V Ion Pump power supply. Please visit our products page to learn more about these TWT Test Sets.

Polarity is now offering 300v and 600v, 100W pulse mode power supplies that have extremely low ripple and low output droop. These are industrial power supplies with remote voltage programming, remote ON/OFF, output current limit, on board voltage adjustment, and voltage and current monitoring output. Please visit our products page to learn more about these Pulse Mode Power Supplies.

Polarity has completed its 3rd generation resonate mode high voltage RF source for TOF mass spectrometers. This RF source provides RF tuning for different capacitive loads and provides an output pulse relative to the internal high speed crowbar. The RF source can be tuned from 800KHz to 2MHz depending on the output capacitance. The high speed crowbar shorts the output to less than 30v in 500ns and be configured to trigger on the positive or negative slope of the sine wave. The output trigger can be justed before (pretrigger) the crowbar event trigger or it can be delayed after the crowbar event trigger. The pretrigger is primarily used to eliminate the effects of external equipment's propagation delay. Please visit our products page for more information on Polarity's TOF Mass Spec RF Source.

Third Generation 1MHz, 2.5KV RF Source Complete:
Polarity completed its third generation 1MHz, 2.5KV RF source that integrates with TOF Mass Spec systems. The rack mount RF Source has a built in crowbar system that is connected electrically across the RF output. It is used to clamp the RF output to less 30V in less than 500ns. Crowbar triggering can be accomplished before the output extraction pulse so that system propagation delay can be accounted for to successfully detect and analyze negative ions. This will enable the BIOresearch firms to look at different proteins with TOF Mass Spec technology.
