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.
