Introduction
The EX752M is a dual output 300 watt PSU with Multi Mode capability in a compact and -
attractive case.
The Multi Mode capability enables it to operate as a dual power supply with two independent and -
isolated outputs, or as a single power supply of double the power. As a dual, each output
provides 0 to 75V at 0 to 2A (Mode A). As a single the output can be selected as either 0 to 75V
at 0 to 4A (Mode B) or 0 to 150V at 0 to 2A (Mode C). In single modes, the unused half of the
unit becomes completely inoperative and its displays are blanked.
The EX series incorporates separate digital voltage and current meters on each output. The
meters use bright 14mm (0.56”) LED displays and have an update rate of 4 per second providing
near instantaneous response. Simultaneous metering of voltage and current provides accurate
information “at a glance” and avoids any possibility of misinterpretation. When an output switch is
set to “off”, the current limit setting is displayed enabling conditions to be set before the load is
connected.
Excellent line and load regulation are matched by low noise and good transient response. High
power efficiency ensures that the unit remains cool without any fan noise.
The EX752M has been designed to meet the stringent requirements of relevant IEC standards
for safety and EMC, including harmonics emissions. All outputs are intrinsically short circuit proof,
and are protected against external voltages and reverse currents.
