Model DFA-100
Dual Channel Analog Difference Amplifier
- converts two channels of two-wire analog inputs to two single ended outputs for A/D converter / data acquisition system applications
- -5V DC to +5V DC input to -5V DC to +5V DC output
- provides over +/- 100V common mode rejection (not isolated)
- economical alternative to commercially available isolation amplifiers (under $150 vs. up to $1000)
- screw down terminals for easy connection to analog signals
- designed for use with APM, Inc. PWM Controllers – all Model 20X and 201-XX versions
- use with the PWM Controller operated in the Analog Input Mode
- eliminates common ground connection between the system transmitting the analog control signal and the power source for the PWM Controller and the device under test
- includes amplifiers for both frequency and duty cycle analog control in ONE package
- connects directly to PWM Controller analog input connector, no external power required
- enclosed unit for use with PWM Controller, includes pigtail connector
- warranty: guaranteed for 1 year for manufacturer defects
- OEM PCB based only version available, request quotation
- Order Number: DFA-100 or DFA-100N ('N' suffix for no PWMC wire harness)
