描述 Description

The DTL22A is an isolated (500Vdc), near-ideal (ZIN = ZOUT ≥ 10MΩ), analog/ voltage-controlled current sink. Its 0-20A output/load current is straightforwardly \"programmed\" by applying a 0-10V input. The control signal can be generated by circuits as simple as the wiper of a trimpot or as sophisticated as programmable logic controllers (PLC’s) or analog-output computer I/O boards (D/A boards). The DTL22A supports any combination of IOUT = 0-20 Amps and VOUT = 2.5-50 Volts. Its thermally efficient, metal package, when properly heat sunk, can dissipate output/load power up to 100 Watts.
