the ex752m is a dual output 300 watt psuwithmulti-mode capability. this enables it to operate as a dualpowersupply with two independent and isolated outputs, or as asinglepower supply of double the power.
as a dual, each output provides 0 to 75v at 0to2a (mode a). as a single, the output can be selected as either 0to75v at 0 to 4a (mode b) or 0 to 150v at 0 to 2a (mode c). insinglemodes, the unused half of the unit becomes completelyinoperativeand its displays are blanked.

voltage/current ranges
2 x (0 to >75v; 0 to >2a) (300wnominalpower)
multi-mode operation
three modes of operation can be selected viaarotary switch:
mode a: two independent and isolatedoutputs(75v/2a each).
mode b: one output of double thecurrentcapability (75v/4a).
(unused output is disabled and its displays are blanked).
mode c: one output of double thevoltagecapability (150v/2a).
(unused output is disabled and its displays are blanked).
output setting & control
voltage setting: by coarse andfinecontrols.
current setting: by singlelogarithmiccontrol.
output mode: constant voltage orconstantcurrent with automatic cross-over. ccindicator inconstant current mode.
output switch: electronic, non isolating.presetvoltage and current limit displayed when output off.
output performance
ripple & noise: typically <2mvrms,<15mv pk-pk (cv mode, 20mhz bandwidth)
load regulation: modes a and b - <0?01%;modec - <0?1% + 2mv (90% load change)
line regulation: <0?01% of maximum outputfor10% line change.
transient response:<<spanlang=en-gb>200?s to within 50mv of setting for a5% to 95%load change.
temp. coefficient: voltage:typically<100ppm/?c.
output protection
output protection: outputs willwithstandforward voltages up to 85v/170v.
over-voltage trip operates above these levels. reverse protectionbydiode clamp for currents to 3a.
output connections
output terminals: high voltagetouch-proofterminals.
terminals can accept standard 4mm plugs,forkterminals and bare wires.
