1 INTRODUCTION
1.1 DESCRIPTION
The Series 500A/102A/152A/202A are High Voltage Switching Power Supplies
designed specifically for charging capacitors in laser systems and other pulsed power
applications. The 500A provides 500 J/s. the102A is 1000 J/s, 152A is 1,500 J/s, and
the 202A provides 2000 J/s of average power and can be paralleled indefinitely for
higher total system power. Lambda EMI also offers the 402 Series, 802 Series, and
303 Series rated at 4,000, 8,000 and 30,000 J/s respectively.
The 500A/102A/152A/202A power supplies incorporate a new high-frequency IGBT
parallel resonant inverter topology for efficient generation of the output power. A high-
performance control module precisely regulates the output voltage, automatically
compensating for line, load, temperature, and rep rate variations. Normal external fault
conditions such as line dropout open or short circuit load, HV arc and over-
temperature will not damage the unit. The latest development in the parallel resonant
inverter topology and control circuitry also drastically improves pulse-to pulse
repeatability by reducing the ripple or bucket eff-ect even at very high pulse
repetition frequencies. The output voltages of the 500A/102A/152A/202A supplies are
fully adjustable over each range.

2.24 ORIENTATION
Power supplies >6kV with Oil H.V. section must be operated in upright position. i.e.
The mounting bracket is parallel to the ground plane.































NOTE: 102A, 152A power supply with suffix 110 at 100-120VAC
must be operated with internal 20A fuses F1 & F2 (on inverter bd)
replaced by copper bus provided with the supply. Use external
30A UL/VDC approved fuse/circuit breaker.
