The E220 Series DC/AC inverter from Endicott Research Group (ERG) Inc. combines up to 12W of output power with the company’s 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 2,300Vrms in a compact, low-profile PCB-mountable package for LCDs ranging in size from 5.7” to 15” diagonal. It uses ERG’s EFD 20 low-profile transformer for a form factor of .60” (15.3mm) high x 1.2” (32mm) wide x 1.56” (39.7mm) long, in a fully vacuum-encapsulated design for maximum resistance to shock, vibration and humidity. The operating temperature rage is 20ºC to 70ºC (-4ºF to 158ºF).
E220 Series inverters address cold starts 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 applications. The inverter operates at efficiencies typically approaching 80 percent, and is designed and tested using the actual OEM LCD display assembly to ensure system compatibility. Customized magnetics are self-shielding to minimize EMI and RFI interference.
The encapsulating 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 PCB is a “high voltage” consideration.
Red Lion’s G306A operator interface panel features a TFT active matrix display to provide desirable contrast, brightness and overall readability for easy viewing in challenging applications. The 5.7” 256-color QVGA 320 x 240 pixel LCD display also offers three front-panel LED indicators and a five-button keypad for on-screen menus. In addition, the G306A arrives standard with an Ethernet port, USB programming port, support for up to five high-speed serial ports, integrated protocol converter, built-in Web server, standard CompactFlash socket and IT-ready data logging.
Users can enter data on the interface panel through the resistive analog touchscreen or front-panel keypad. The model comes with an onboard memory of 8MB, and it can be configured using the company’s Crimson Programming Software. The G306A is suited for collecting and displaying data or interfacing with a variety of devices including PLCs, PCs, drives, PID controllers and others.
