ELTEST s EL2A-LC is an optically isolated, digitally programmable, serial-
input electronic load designed for use in burn-in, characterization and test of today s
low-voltage power supplies and power components. The EL2A-LC is essentially a
digitally controlled current source that can sink currents from 0 to 20 Amps, at loading
voltages as low as 0.6 Volts, up to a maximum power of 100 Watts.
The EL2A-LC accepts a serialized, 12-bit, CMOS/TTL-compatible, digital input
word easily supplied by any standard digital I/O card. The EL2A-LC optically isolates
(500Vdc) the digital data, latches it, and presents it to an on-board, 12-bit, digitalto-
analog (D/A) converter. The D/A output drives a near-ideal (10MO min. output
impedance), voltage-controlled current source. One LSB (least significant bit) of the
D/A corresponds to a 5mA increment (0.025% of 20A) in load current. The EL2A-LC
guarantees a 10mA max. offset error and a 0.4% max. gain error. It has an impressive
full-scale step response time of 100 sec and can be updated at rates to 20kHz.
The EL2A-LC operates from a single +5V and draws a mere 150mA. It is housed
in a thermally efficient, 2" x 2" x 0.5" metal package that has an aluminum baseplate
with through-hole spacers for easy pcb mounting and/or heat-sink attachment.
When operating with constant currents up to 20 Amps, the EL2A-LC has an
output compliance voltage of 0.6 to 50 Volts. Should the output/load voltage drop below
the 0.6V minimum required for proper biasing, an internal monitoring circuit activates the
ELTEST s electronic loads and their companion controller boards and software are
outstanding building-block components for power-supply (AC/DC and DC/DC converters)
and power-component (diodes, FET s, etc.) burn-in and test systems. They are an
extremely reliable, cost-effective solution that enables you to quickly configure fl exible,
impressively accurate systems.
