AMPBOX Signal Amplifier

AMPBOX is a current loop amplifier for the complete range of solar radiometers.

The AMPBOX Amplifier allows for an extended temperature range and negative inputs.

Description

Most radiometers have no power supply, the measured radiation is used to create an output signal in the mV range and amplification is often required, especially when signal cables of more than 50 m are used between the radiometer and data collection equipment.

The input and output of the AMPBOX are galvanically isolated to minimize feedback and to protect the data collection equipment. When installation is in EMC-unfriendly environments, amplification can prevent interference problems.
The 4 to20 mA interface makes it easy to connect to most data collection equipment. An output of 2 to 10 Volt can be created with the use of a 500 Ω resistor and a suitable power supply.
