PRESENTATION

The EFS 83708370837083708370 module is apower driver for piezoelectric injectors.It features different drivingmodes and advanced functions making it adaptable to most of the injectors available on the market.

EFS 8370

ADVANTAGES

?

Opening and closing voltage can be set independently between -200 V to +200 V

?

Maximum current can be set from -20 A to +20 A

?

Current slope can be set between 0.1 A/µs to 10 A/µs

?

Enough power to deliver 250 injections per second

?

Internal pulse generator.

SYSTEM DESCRIPTION

The driving parameters of the injector can be set via an RS232 or RS485 (4 wires link, using the MODBUS protocol:

?

MODBUS identification on the front panel

?

Daisy-chaining of racks by means of the RS485 link

?

PC supervision software available on demandThe injector driving can be started:

?

by an external input

?

by an internal pulse generatorThree driving methods are available as standard (see the examples above).Other modes can be added upon request.The « injector opening » voltage can be fixed or can changeby linear regression basedupon an analog input, the image of an external physical phenomenon.The equipment is protected against overcurrents, short-circuits and overheating.
IPOD PIEZO

SOFTWARE

WinIPOD piezo (EFS1764) is a graphicinterface enabling the complete parameter management (currents, voltages, time) necessary for driving the injector.This software runs under Windows98 ,Windows2000 , WindowsXP and
