This line of power supplies is designed for noise reduction, instrument accuracy, data consistency and stable communication. The ECS economy power supply is an ideal process loop component for use with noise prone two-wire transmitters and data communications equipment. The DPS DIN power supplies can power two-wire transmitters and data communication modules. The DPS 240 can be used to power a maximum of 12 4-20mA loops, while the DPS 1200 can power a maximum of 60 4-20mA loops. The SMP surface-mount power supply is a compact, precision-regulated, linear dc instrument unit that powers large numbers of two- and four-wire process instruments.
