Littelfuse: LSP10GIHP Series – Thermally Protected Surge Protective Device

LSP10GIHP Series Surge Protection Modules are designed for use in outdoor and commercial LED lighting fixtures for transient overvoltage protection.
The 20KV, 10kA surge handling capability will enhance the LED lighting fixture’s surge immunity and extend its operating lifetime.
LSP10GIHP Series modules are constructed with Littelfuse thermally protected varistor technology. A built-in thermal disconnect function provides additional protection to prevent catastrophic failure and fire hazard even under the extreme circumstances of varistor end-of-life or sustaining over voltage conditions.

These modules have UL 1449 4th Edition Type 4 recognition and are IEC61643-11 Class II and EN61643-11 Type 2 certified. They meet US DOE, ANSI C136.2-2015 and ANSI C82.77-5. Extreme Level (Category C High, 20kV, 10kA).

The LSP10GIHP Series features a built-in LED indicator that notifies the lighting technician when replacement of the module is needed. It is available in series-connected format only with a choice of 277V or 480V maximum voltage rating.

Triad – Do Your Plug-In Wall Transformers Meet New DOE Standards?

Triad LOGO

Plugin wall transformers

As of February 10, 2016, the United States Department of energy (DOE) Level VI Efficiency Standard is in effect. The team at Triad Magnetics has been hard at work overhauling our plug in wall transformers to meet these demanding efficiency requirements. We’re happy to announce that Triad Magnetics’ plug-in wall transformers have achieved level VI efficiency! Improvements include:

  • More stringent performance standards
  • Extremely low no-load power draw

We’ve recently published a blog post that will go into more detail about these exciting new redesigns. You can read about them by clicking here .

New 1000 W Module for MicroMP Configurable Power Supply…


New Artesyn 1000 W Module for MicroMP Configurable Power Supply Can Replace Four Individual Modules at Half the Price

Artesyn Embedded Technologies today announced a new 1000 watt module for its next generation MicroMP (µMP) configurable power supply.

Previously, applications that require a single output voltage around 1000 W would have used four single slot modules tied in parallel, but this new 1000 W module replaces those four modules with a single three-slot module, not only saving a slot but also half the cost of the previous four-module solution.
