Overview
AMPBOX is a current loop amplifier for the complete range of solar radiometers. The input and output of the AMPBOX are galvanically isolated to minimize feedback and to protect the data collection equipment. The 4 to 20 mA interface makes it easy to connect to most data collection equipment.

Detailed Description
AMPBOX is a current loop amplifier for the complete range of solar radiometers. 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 50m are used between the radiometer and data collection equipment.
The input and output of the AMPBOX are galvanicly 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 to 20mA interface makes it easy to connect to most data collection equipment.
