The DTL23A is an isolated (500Vdc), near-ideal (Zin = Z
OUT
>= 10M
), 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 I
OUT
= 0-2.0 Amps and V
OUT
= 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's
output/load current.
The DTL23A is packaged in a small (2" x 2" x 0.5"), thermally efficient 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 configure impressively accurate
systems.
