Regulation

(Line or Load)

Voltage: 0.05% of maximum rated output +2mV

Current: 0.1% of maximum rated output

Transient response

Typically recovers in 1ms to within 1% of steady-state

output voltage (greater than 50% Vmax) for a 70-

100% or 100-70% load change

Stability

+/-0.05% of maximum voltage or current over 8 hours

after 15 minute warm-up time at fixed line, load and

temperature

Temperature coefficient 0.02%/°C of maximum output voltage

0.03%/°C of maximum output current

DLM Series

3000-4000 WATTS PROGRAMMABLE DC SUPPLY

OPERATING

Efficiency

5-8V Models: 82% typical

16-80V Models: 87% typical

150-600V Models: 85% typical

Remote sense

The maximum allowed sense line drop is 2V for 5V, 8V

and 16V models and 5V for all other models

Remote sense protection

Unit will not be damaged due to misconnection of the

remote sense leads

Remote programming

Voltage, current (0-100%) and OVP (5-110%) of full

scale can be programmed by selectable 0-5VDC, 0-

10VDC, or 0-5k

Ω

Remote monitoring

Voltage or current can be monitored with user-

selectable ranges, 0-5VDC or 0-10VDC

Over-voltage protection Crowbar type adjustable from 5-110% rated output

using front panel control

(local or remote program selectable)

Displays and indicators Two 3.5 digital LED displays indicate output voltage,

output current and over-voltage setting. LED indication

for power on, shut-down, remote, overvoltage, over-

temperature and front panel lockout, constant voltage

and constant current modes. IEEE-488.2 indicators

include error, SRQ and address

Software

LabVIEW® driver for M9E/M85

(Contact Powerbox)

Built-in protection

Over-voltage (resets by cycling the Enable/standby

switch), over-temperature (will automatically reset)

Operational features

Master/slave parallel operation, up to 2 units can be

connected in parallel with active current sharing

control to within 10% of each supply. Series operation,

up to 3 units of the same model type can be connected

in series (consult manual). Negative terminal rated at

150Vmax Above ground
