Description

     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 effcient, 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 fexible, 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 signifcant bit) of the D/A corresponds to a 0.5mA change in the DTL23A's output/load current.

       The DTL23A is packaged in a small (2" x 2" x 0.5"), thermally effcient metal package incorporating an aluminum baseplate with through-hole mounting inserts.  It is powered by a single +5V supply and draws a mere 150mA.

       The DTL23A has an output compliance voltage of 2.5-200 Volts.  Should the output/load voltage drop below the 2.5V required for proper biasing, an internal monitoring circuit activates the DTL23A's  output Fault line.   See DATEL's DTL22A-LC for compliance voltages as low as 0.6V.

       The DTL23A and other electronic loads, controller boards, and software from DATEL are outstanding building block components for power-supply burn-in and test systems.  They are extremely reliable, cost-effective solutions that enable you to quickly confgure impressively accurate systems.
