DTL22A Model Voltage-Controlled

20 Amp 100 Watt, Electronic Loads

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 I^OUT= 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.

The easy-to-use DTL22A 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, 1ꢀ 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 5mA change in the DTL22A’s output/load current.

The DTL22A is packaged in a small (2" x 2" x 0.5"), thermally efﬁcient metal

package incorporating an aluminum baseplate with threaded inserts. It is powered by

a single +5V supply and draws a mere 150mA.

Applications

■

■

Static/dynamic power-supply burn-in

The DTL22A has an output compliance voltage of 2.5-50 Volts. Should the

output/load voltage drop below the 2.5V required for proper biasing, an internal

monitoring circuit activates the DTL22A’s output Fault line. See DATEL’s DTL22A-LC

for compliance voltages as low as 0.6V.

The DTL22A 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.
