Excelsys Technologies new Reactive Load powerMod series of plug-in DC modules are optimised for Reactive Loads

Excelsys Technologies today introduced the Reactive Load powerMod series of plug-in DC output modules that are optimized for driving DC motors and other reactive loads. Backed by a five-year warranty, the new XgR and XgT powerMods offer design engineers increased system robustness and reliability by providing complete protection where loads can generate high levels of reverse energy, such as in industrial and medical applications.

Frequently, 24V and 48V rails are used to power pumps, motors, fans, compressors, capacitor banks, batteries, or combinations of inductive and capacitive loads, in complex systems that come with unique system design challenges. The new XgR and XgT powerMods offer proven performance and reliability under harsh conditions and challenging applications, while still maintaining flexibility, efficiency and all the benefits — including forward and backward compatibility— of Excelsys’ existing UltiMod, Xgen, and XF platforms. 088- Excelys XgR and XgT

The XgR and XgT power supply modules come equipped with a built-in OR-ing function and an anti-reversal diode. The OR-ing circuit, utilizing a MOSFET to maintain high efficiency, offers N+1 redundancy to the user when the powerMods are used in parallel operation. The anti-reversal diode across the output, which is rated for the full current of the module, offers increased ruggedness when the modules are used in reactive load applications.

The new XgR and XgT powerMods can deliver output voltages from 8.0 to 58 volts. The feature-rich powerMods provide a suite of output signals and user-configurable functions, including local and remote output voltage adjustment; adjustable current limit; dynamic voltage trim/adjust, alternative current-limiting techniques; and inhibit/enable functions. The modules can be connected in series or parallel, enabling them to achieve compliance with all voltage/current requirements. The modules’ additional standard features and options are: dual safety approvals (UL/EN60950 2nd edition and UL/EN60601-1 3rd edition and -40°C start-up temperature. Standard features for medical applications include leakage current (300 and 150 micro-amps), 2 MOPP, and 4KV isolation. They also include OVP, OTP, OCP, MIL STD-810G compliance with shock and vibration. All products offer highest efficiency (up to 92%) and are SEMI F47 compliant.

Typical applications for the XgR and XgT powerMods include medical (e.g., clinical diagnostic equipment, medical lasers, dialysis equipment, radiological imaging, and clinical chemistry) and industrial (e.g., test and measurement, industrial machines, automation equipment, printing, telecommunications, audio equipment, harsh industrial electronics, hi-rel/MIL COTS and radar).
“Our new XgR and XgT Reactive Load powerMod series ensures that our market-leading plug-and-play, user-configurable power modules can be used in the harshest of electrical environments,” said Gary Duffy, Excelsys CEO. “By providing protection against the reverse energy produced by reactive loads, we provide our customers an off-the-shelf product to meet the most demanding applications.”
