EL-R Series - continued
Single, dual or triple outputs
The EL-R series includes six single output models plus one dual output
and one triple output model.
The EL302RD has two independent and isolated outputs each with a 0
to 30V, 0 to 2A capability and its own on-off switch. The outputs can
be wired in either series or parallel to provide voltages up to 60 volts
or currents up to 4 amps.
All outputs are intrinsically short circuit proof, and are protected
against external voltages and reverse currents.
Variable voltage auxiliary output
The EL302RT incorporates a third output fully variable between 1.5V
and 5.0V with a fixed current limit of 2A.
The set voltage can be measured at the press of a button using the
digital meters.
* Note that this third output uses switch-mode post regulation.
Alternative power supply series
If the EL-R series does not exactly fit your requirements, TTi offers ten
other PSU series totalling around 60 models. The closest models to the
EL-R series are:
New PL & PL-P series
Advanced linear regulated PSUs of ultra-compact size offering up to 90
watts per output. Features include lockable analog controls, variable
voltage span, and 0.1mA current resolution.
The P versions include remote control via analog, RS232, USB and LAN
interfaces with LXI support. GPIB is available as an option.
EX-R series
The EX-R series has similar features to the EL-R series but uses mixed-
mode regulation to offer power from 175 watts up to 420 watts.
Full details of the EX-R series are included within this brochure.
EL302P/EL302P-USB:
operation via RS-232 or USB
The EL302P is a digitally controlled version of the EL302 with an
isolated RS-232 interface. It offers a low-cost solution for a basic
programmable PSU and will be sufficient for many applications
where the sophistication and complexity of GPIB is not needed.
A simple command set allows remote control of voltage, current
and output enable together with read-back of metering values
and operational status. Local control is via three rotary encoders
providing rapid and accurate setting of voltage and current during
bench use.
The EL302P-USB has similar functionality but is controlled via a
USB interface.
