DATEL’s new DTL2A is an optically isolated, digitally programmable, serial-input,
electronic load. It is essentially a digitally controlled current source that can sink
currents from 0 to 20 Amps, at loading voltages from 2.5 to 50 Volts, up to a maximum
power of 100 Watts. The DTL2A is packaged in a thermally efficient, 2" x 2" x 0.5"
metal package that incorporates an aluminum baseplate with through-hole spacers
for easy pcb mounting and/or external heat-sink attachment.
The DTL2A accepts a serialized, 12-bit, CMOS/TTL-compatible, digital input word
easily generated by any standard digital I/O card. The DTL2A buffers and then opti-
cally isolates (500Vdc) the digital input data before storing it in a register and present-
ing it to an on-board, 12-bit, digital-to-analog (D/A) converter. The D/A output drives
a near-ideal (10MΩ minimum output impedance), voltage-controlled current source.
One LSB (least significant bit) of the D/A converter corresponds to a 5mA increment
(0.025% of 20A) in load current.
The DTL2A features a max. ±5mA offset error and a max. ±0.1% gain error. It
has an impressive full-scale step response time of 100µsec and can be operated
dynamically at update rates up to 20kHz. Powered by a single +5V supply, the DTL2A
draws a mere 150mA (maximum).
While operating in the constant-current mode up to 20 Amps (100W max. power),
the output compliance voltage of the DTL2A is 2.5 to 50 Volts. Should the output/load
voltage drop below the 2.5V minimum required for proper biasing, an internal monitoring
circuit activates the DTL2A's output Fault line. See DATEL’s DTL2A-LC for compliance
voltages as low as 0.6V.
DTL2A’s 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 an extremely reliable, cost-effective solution that enables you to quickly
configure impressively accurate systems.
