ESS120 AC/DC Proportional Amplifier
The ESS120 Sending Unit provides a reduced cost alternative to the DGO style rotary inductive transformers.

The ESS120 utilizes a voltage command from a high life potentiometer and converts it to a high voltage DC signal that emulates the signal found in our DGO 1, 2 & 3 rotary differential transformer.

DETAILS
Applications
Extremely high life contactless rotary differential transformers are preferred where duty cycle is high and where the transmission of an AC signal is a requirement. For use in applications where where a variety of output characteristics are necessary. Suitable for crane applications where a slightly higher or lower reference voltage may be needed.

Features
» Microprocessor based technology
» Configurable to emulate 3 DGO models.
» Separate sending and converting modules.
» Sending unit generates high voltage output for noise immunity over long distances
» Converting unit to reduce signal voltage to a reference signal at the drive, such as +10-0-+10V or -10-0-+10 volt output.
» Offset outputs for hoist application available upon request.
» Special output curves upon request.
