Inverter Powers LC Displays from Cold Starts

May 2, 2007
The new E220 Series DC-AC inverter from Endicott Research Group combines up to 12 watts of output power with ERG’s unique vacuum-encapsulated design to ensure reliable CCF lamp ignition for LCDs used in outside, cold storage or other low-temperature environments. The E220 provides starting voltages of up to 2300 Vrms in a compact, low-profile, PCB-mountable package for LCDS ranging in size from 5.7" to 15" diagonal. It utilizes ERG’s EFD 20 low-profile transformer for a form factor of only 0.60" (15.3 mm) high x 1.2" (32 mm) wide x 1.56" (39.7) mm long, in a fully vacuum-encapsulated design pioneered by ERG that ensures maximum resistance to shock, vibration & humidity. Operating range is -20º to +70ºC (-4º to 158º F). E220 Series inverters provide the ideal cold-start solution for CCFL-backlit LCDs that provide engine speed, ground speed, fuel consumption, oil pressure, coolant temperature and other critical information for vehicles used in heavy-duty, off-highway and mobile equipment - more - applications. Examples include forklift trucks in cold storage warehouses, agricultural and construction equipment used in harsh outside environments, EMS vehicles, and marine equipment. ERG’s E220 vacuum-encapsulated inverter operates at high efficiencies, typically approaching 80%, and is designed and tested using the actual OEM LCD display assembly to ensure system compatibility. ERG’s customized magnetics are self-shielding to minimize EMI and RFI interference. The encapsulation of the inverter enables designers to better package it with respect to the rest of the system – only the pins are exposed, so only the bottom of their printed circuit board is a "high voltage" consideration. This is especially useful for embedded designs. All ERG E220 inverters carry a one-year warranty and are designed and manufactured in the U.S.A. • Only 0.60" High • Starting Voltage to 2300 Vrms • PCB Mountable • Fully Encapsulated • Up to 12 Watts of Output Power • Ideal for Cold Starts
