NEV Electronics LLC
What we do
NEV Electronics LLC provides electronics engineering consulting services, products for our clients and our own line of electronic products. We
specialise in lighting controls, ballasts, building automation, industrial and mobile control. Select the Services button for our consulting capabilities
and the Products button for our line of products.
NEV, as part of GV Controls, co-invented and co-designed the Green Dimmer, a simple to use and low cost controller for 0-10V dimming ballasts.
The light level is set by flicking the existing light switch. The Green Dimmer can be retrofit with no new wiring to the fixture. See GV Controls
CEDR: Cost Effective Demand Response system
"The California Lighting Technology Center of the University of California, Davis, in conjunction with Benya Lighting Design and NEV Electronics
LLC, is pleased to announce the development of a new system for electrical power system Demand Response (“DR”). This system is capable of
being quickly implemented at low cost and can be used to shed unnecessary lighting, appliance, air conditioning, and almost any other electric load
during periods of Stage 1, 2 or 3 power emergencies.
The principal feature of the system is the ability to retrofit into existing buildings of all types, from residences to hotels, office buildings, and even
industrial sites. No major rewiring is required; transmitting devices are installed at the electrical panel and receiving devices, including special wall
switches, are installed at loads. Loads are shed upon command with the option of power emergency level, permitting prioritizing and choice by the
Unlike competing and foregoing concepts, this development uses low cost, robust devices, easily installed in existing or new buildings, and is
capable of plug and play operation. It has been specifically developed to solve California’s power crisis issues through safe, planned and staged
load shedding, rather than adding generation capacity or staging rolling blackouts. The simplicity of the system lends itself to broad dissemination
through utility rebate programs and other mass marketing programs.
A proof of concept demonstration device has been developed and operates properly."

NEV designed and produced a demonstration system that has been installed at CLTC. An RF remote is used to trigger the DR event to simulate the
wide variety of triggers that may be preferred by individual utilities. The CLTC site photographs show that only the existing electrical wiring is
required when a wireless DR trigger signal is used.. Patent applied for.
CEDR development towards commercialization is proceeding under Project 3 of CEC's PIER LRP2 Lighting California's Future.
