The XPH 42-10 is an exceptionally compact and lightweight single output laboratory dc power
supply providing 0 to 42V at 0 to 10A.
The XPH 42-10 uses mixed−mode regulation technology which combines switch−mode
pre−regulation with linear post−regulation. Special techniques are used to maintain very high
efficiency whilst achieving noise levels that are close to that of a pure linear regulator.
Excellent line and load regulation are matched by low noise and good transient response. High
resolution controls allow accurate setting of voltage and current levels. Remote sense terminals
are provided so that good regulation can be maintained across remote loads at high currents.
The output operates in constant voltage or constant current mode with automatic cross-over and
mode indication. There is a DC output on−off switch.
The XPH 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 the output switch is
set to "off", the current limit setting is displayed enabling conditions to be set before the load is
connected.
The XPH series has been designed to meet the stringent requirements of the latest relevant IEC
standards for safety and EMC. All outputs are intrinsically short circuit proof, and are protected
against external voltages and reverse currents.
