Product Overview
This chapter provides an overview of the PPS LMX Series® programmable power sources. It
introduces the reader to general operating characteristics of these power supplies.
3.1
General Description
The Pacific Power Source (PPS) LMX Series® power source is designed to provide accurate,
stable and clean AC power to a unit under test.
This series of programmable AC power sources features models with power ratings from
500 VA to 6000 VA with paralleling capability to 30kVA. All systems are designed to fit into a
standard 19-inch rack. These systems are suitable for use as frequency changers as well as
sophisticated test power generators.
All systems are configured with and advanced high performance controller that offers full
programmability of the AC power source. This controller allows control of voltage and
frequency and also allows the user to simulate virtually any transient (including sub-cycle
waveform disturbance) required for testing today's modern electronic equipment.
The LMX controller is also equipped with a high performance single or three phase power
analyzer with deep acquisition memory for measurement and waveform capture of output
parameters.
The standard output voltage range for most of the LMX-Series is 0-135 Vac L-N.
Additionally, Models 112LMX and 312LMX can operate from 0 to 150 Vac L-N.
Optional output transformers are available to provide higher output voltages. Voltage ratios
up to 2.5:1 are readily available. Other transformer ratios are available by special order.
The PPS LMX Series® power supply can be operated from the front panel (manual mode) or
using RS232, USB,LAN (Ethernet) or GPIB remote control.
