Specifications
OPERATING
INPUT
Efficiency
5-8V Models: 82% typical
16-80V Models: 87% typical
150-600V Models: 85% typical
Input Voltage
3KW:180-264VAC, single or three phase
(<200VAC range limited to 40°C maximum) 4KW:180-
264VAC, three phase (<200VAC range limited to 40°C
maximum)
Remote sense
The maximum allowed sense line drop is 2V for 5V, 8V
and 16V models and 5V for all other models
Frequency
47-63Hz for both single and three phase input
Unit will not be damaged due to misconnection of the
remote sense leads
Remote sense protection
Power Factor
0.95 typical with three phase input
0.98 typical with single phase input
Remote programming Voltage, current (0-100%) and OVP (5-110%) of full
scale can be programmed by selectable 0-5VDC, 0-
10VDC, or 0-5kΩ
ENVIRONMENTAL
Operating temperature 0°C to 50° (No De-rating)
Remote monitoring
Voltage or current can be monitored with user-
selectable ranges, 0-5VDC or 0-10VDC
Storage temperature
Cooling
-40°C to 65°C
Internal fan with over-temperature protection
Over-voltage protection Crowbar type adjustable from 5-110% rated output
using front panel control
OUTPUT

See table
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
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
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)
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
+/-0.05% of maximum voltage or current over 8 hours
after 15 minute warm-up time at fixed line, load and
temperature
Stability
Operational features
Temperature coefficient 0.02%/°C of maximum output voltage
0.03%/°C of maximum output current
