Page 5: Introduction
1. INTRODUCTION Congratulations on your purchase of a PA10A power amplifier! This manual covers important information related to the use and operation of the PA10A power amplifier. Please review this manual carefully as it contains important information regarding the safe and proper operation of the amplifier. -
Page 6: Overview
2. OVERVIEW The PA10A power amplifier has been designed for easy operation via front panel controls. External input and output connections are found on the rear panel. Internal over-temperature and over-current protection assure continuous operation at full rated power without concern for damage to the amplifier. -

Page 9: Installation
The amplifier should never be operated without proper earth-grounding or with either of its covers removed. 3.1 Location Considerations The PA10A power amplifier is designed to be used on a standalone workbench or mounted on a standard 19-inch, 2U instrumentation rack (480 mm × 88.9 mm [19 in. × 3.5 in]). -

When changing fuse: Replace the fuse on both sides of the fuse holder with a new 3AG fuse of the same rating (5A 250V for 115VAC or 3.0A 250V for 230VAC) (Figure 3-5). Figure 0-5 Model PA10A | Wilcoxon Sensing Technologies Page 10... -
Page 11: The Power Amplifier, Matching Network, And Shaker Cables
All Wilcoxon shakers except the F7-1 piezoelectric shaker are standardized for use with the Wilcoxon PA10A power amplifier and include the cables necessary to do so. The PA10A is not capable of driving the F7-1 to its full frequency range and should not be used unless measurements are only being made up to 40 kHz. As such, the N8HFS matching network, which is designed for use with the F7-1, includes a cable to mate with the Wilcoxon WST7B3 power amplifier. - Page 12 Matching Standard cable Shaker matching network (N8HFS network connecting to model cable mates with WST7B shaker None None R1-8C-8C-J93-10 None None R4M-8C-8C-J9B-10 None None R4M-8C-8C-J9B-10 R22-8C-8C-J9B-5 N7FS R4-4M-J9-10 R22-8B-8B-J9B-5 N8HFS R4-4M-J9-10 F7-1 Model PA10A | Wilcoxon Sensing Technologies Page 12...
