Chapter 1 Overview
The IP500 is a universal 500 mA board level driver. Designed for use within higher
level assemblies, while being value priced as a laboratory diode driver. This
versatile device can easily and safely control all Laser Diode / Photo Diode pin
configurations in 5.6 mm and 9 mm lasers. Operating in constant current or
constant power mode, this driver can be enabled on the board itself or over a
remote switch connection. Connections are provided for remote interlocks and
remote monitoring. Wire harnesses for all required connections are provided with
the unit.
1.1. Features
Accepts photodiode feedback currents of up to 2.0 mA.
Pin configurations and operating modes are easily set using on board
jumpers.
Current and power limits are set using individual 25-turn potentiometers.
Current or power is adjusted using a 25-turn potentiometer.
Easily accessible test points allow analog monitoring of the injection
current and photodiode feedback current as well as the current and
power limit settings.
Laser diode inputs are shorted during idle operation to protect the
device.
Three indicators display whether the laser is enabled, operating at
current limit, or in an alarm shutdown condition.
Automatic alarmed shutdown when laser connection is open or
reversed.
Operates from ±5 VDC.
Analog modulation up to 50 kHz.
Separate ENABLE switch turns laser on and off, no need to power down
the entire unit.
