Overview

M550221-01 Rev AA

1-5

Parameter

Specification

Output Voltage Fall Time

(with rated load, resistive; current fall
time same)

10 ms, maximum, from 90-10% of programming change from
rated output voltage to zero for 10V-30V models;

contact factory for values of specific models

Output Voltage Fall Time

(with no load)

50 ms, maximum, from 90-10% of programming change from
rated output voltage to zero for 10V-30V models;

1.5 s, typical, from 100% to 10% of programming change from
rated output voltage to zero for 40V-1000V models;

contact factory for values of specific models

Front Panel Meter

Display Resolution

4 digit

Voltage Accuracy

(to actual output)

±(0.15% of rated output voltage + 0.1% of actual output + 1 digit)
for 10V-30V models;
±(0.1%, maximum, of rated output voltage + 1 digit) for
40V-1000V models

Current Accuracy

(to actual output)

±(0.4%, maximum, of rated output voltage + 1 digit)

Front Panel Programming

Voltage

±(0.1% of rated output voltage + 0.1% of actual output voltage)
for 10V-30V models;

±0.1%, maximum, of rated output voltage for 40V-1000V models

Current

±(0.4% of rated output current + 0.1% of actual output current)
for 10V-30V models;

±0.4%, maximum, of rated output current for 40V-1000V models

Overvoltage Protection (OVP)

±1%, maximum, of rated output voltage

Remote Sensing

Connection

Voltage accuracy/regulation specifications apply at the point
where the remote sense leads are connected.

Line Drop

1 V, maximum per line for 10V-20V models;

1.5 V, maximum per line for 30V model;

5%, maximum of rated output voltage per line for models, 40V to
less than 160V;

2%, maximum of rated output voltage per line for models greater
than or equal to 160V;

greater level of line drop is allowed, but output voltage regulation
specifications no longer apply.

Line Drop Effect on Output
Voltage

Rated output voltage applies at the rear panel output terminals,
and line drop voltage subtracts from the voltage available at the
load terminals

Remote Analog Interface

Programming Accuracy

Voltage

±0.25%, maximum, of rated output voltage for 0-5 VDC range,
and ±0.5%, maximum, for 0-10 VDC range

Current

±1.0%, maximum, of rated output current for 0-5 VDC range,
and ±1.2%, maximum, for 0-10 VDC range for 10V-30V models;
