XPH Series - High Power at Low Cost
The XPH Series provides high levels of power at surprisingly low cost. The attractive case style is highly compact using the minimum of bench space. The low weight makes them easy to move about.

Mixed-Mode Regulation
The XPH Series combines switch-mode pre-regulation with linear post-regulation to provide performance comparable with an all linear design. Excellent line and load regulation is matched by low noise and good transient response. High power efficiency makes fan cooling unnecessary (fan used on XPH42-10).

Constant Voltage or Constant Current
The main outputs can operate in constant voltage or constant current mode with automatic crossover and mode indication. Coarse and fine voltage controls are provided. The current control is logarithmic enabling low current levels to be set accurately.

Simultaneous Digital Metering
The XPH Series incorporate separate digital voltage and current meters on each main 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.

Single, Dual or Triple Outputs
XPH Series units are available in single, dual or triple output versions. The XPH35-4D, for example, has two independent and isolated outputs each with a 0 to 35V, 0 to 4A capability. The outputs can be wired in either series or parallel to provide voltages up to 70 volts or currents up to 8 amps. The XPH35-4T has an additional "logic voltage" output with a 5A current capability. This output can be adjusted between 1.5 and 5 Volts.

Output Voltages up to 150V (XPH75-2D)
The XPH75-2D is a dual output 300 watt power supply with Multi-Mode capability. This 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. As a single the output can be selected as either 0 to 75V at 0 to 4A or 0 to 150V at 0 to 2A. In single modes, the unused half of the unit becomes completely inoperative and its displays are blanked.

Ready for Low-Voltage Logic (XPH35-4T)
To reflect the increasing usage of low-voltage logic devices, the third output of the XPH35-4T can be adjusted between 1.5 and 5 Volts.

Higher Current Models (XPH18-10, XPH42-10)
The 10 Amp models include switchable remote sensing and extended voltmeter resolution.

Safety and Reliability
The XPH Series has been designed to meet the stringent requirements of relevant IEC standards for safety and EMC. All outputs are intrinsically short circuit proof, and are protected against external voltages and reverse currents.
