PROGRAMMABLE DC POWER SUPPLY

MODEL 62000P SERIES

Chroma's new

power supplies offer many unique advantages

for ATE integration and testing. These advantage

include a constant power operating envelope,

precision readback of output current and voltage,

outpu t trig ge r signals as wel l as the ability to

cr eat e co mpl ex DC tr ans ien ts wav eforms to

test device behavior to spikes, drops, and other

vo lta ge devia tio ns.D esi gne d for aut oma ted

testing DC-DC conver ters and similar products,

the

programmable DC supplies.

The

ranging from

to

envelope a single instrument can provide both

high voltage/low current AND low voltage/high

current thereby reducing the number of supplies

needed in typical ATE applications.

ca pabi lit y for accu rat e vol tag e and curre nt

readi ngs. This mea ns systems no longer nee d

com plex shunt/multiple xers to make accurate

read ings of th e UUT's inp ut par amete rs. The

instruments also include I/O ports providing 8

bit TTLs, DC-ON, fault output signal and remote

inhibit as well as a output trigger signal for system

timing measurements.

Another unique capability of the

supplies is th ei r abi li ty to create complex DC

transient waveforms. This capability allows devices

to be test ed to DC volta ge drop out s, sp ike s

and other voltage vari ations mak ing them an

ideal choice for airborne device testing, inverter

testing and other devices which will experience

voltage interrupts. Applications include DC/DC

Converter & Inver ter voltage drop test, engine

start-up simulation, battery automated charging,

electronic product life cycle test, and etc.

P Series also includes 16 bit readback

supplies prov ide the same rated cu rr ent at all output voltages, howe ver, the

provides greater current at lower outpu t voltage s. This means both low voltage/high

current and high voltage/low current UUTs can be tested using a single supply avoiding the

for multiple supplies saving cost and space within typical ATE systems.
