DTL23A

Preliminary ® ® INNOVATION and EXCELLENCE DTL Series DTL23A Model Voltage-Controlled, 2 Amp 100 Watt, Electronic Loads Features 0-10V Input/control voltage 0-2A output/load current 2.5-200V output compliance voltage 0-100W output/load power 10MΩ output impedance 500Vdc Isolation ±1% accuracy under all conditions 200µsec full-scale step response 2" x 2", shielded metal package Operate in parallel for higher power The DTL23A is an isolated (500Vdc), near-ideal (Zin = ZOUT >= 10MΩ), analog/voltage-controlled current sink. It's 0-2.0A ouput/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 DTL23A supports any combination of IOUT = 0-2.0 Amps and VOUT = 2.5-200 Volts. Its thermally efficient, metal package, when properly heat sunk, can dissipate output/load power up to 100 Watts. The easy-to-use DTL23A is an excellent building block for low-cost, fully flexible, power-supply (AC/DC or DC/DC) or power-component (MOSFET's, diodes, etc.) test and burn-in applications. It is accurate (±5mA offset error, ±1% overall accuracy), fast (200µsec full-scale step response), and capable of impressive resolution. If it is controlled with a 12-bit, 0-10V D/A converter, for example, one LSB (least significant bit) of the D/A corresponds to a 0.5mA change in the DTL23A'...
