Time Electronics 9760 Power Amplifier User Manual
Introduction
The 9760 power amplifier has been designed to complement the Time Electronics range of multifunction calibrators. The unit provides an output current suitable for driving even the most demanding analogue meters.
Operation is simple with connection via the front panel terminals. The reference calibrator (for example 5025C) connects to the input terminals. Then the output is connected to the meter. The user then presses the output button.
The amplifier has a gain of x10. So an input voltage of 1 V will produce an output of 10 V.
Due to the output resistance of the amplifier, the accuracy of the output is specified for loads greater than 600 Ω. If loads less than this are present a reduction of 1 mV per 10 mA of load current will apply
Features

- Short circuit protection: 160 mA
Operation
Safety Precautions
High Voltage: The instrument can output high voltage and users should be aware of the dangers involving serious electrical shock.
This instrument is rated as class 1, to protect against electric shock due to fault condition, the IEC C13 power cord supplied, connects the case to the protective ground provided by the local power utility company. An additional PE terminal is provided at the rear for use when the utility ground is unsatisfactory or does not exist. Please consult local regulations.
Mains (Line) Power Supply
The supply power is connected via a standard IEC Euro connector on the rear panel.
The standard voltage supply is 100V – 230V 50/60Hz. There are two protection
fuses mounted in the IEC connector assemble, both are T3.15A slow blow.
Front Panel
Operating Instructions
Ensure the output is off before the reference input, and output are connected.
- The reference input is connected to the lower terminals marked ‘Input’ (see page 7 for input limits).
- The ‘Output’ is connected from the two upper terminals.
- To turn the output on, push the output button.
The output button will illuminate to confirm the output is connected
The amplifier has a gain of x10. So an input voltage of 1V will produce an output of 10V.
Note:
Due to the output resistance of the amplifier the accuracy of the output is
specified for loads greater than 600Ω. If loads less than 600Ω are present a
reduction of 1mV per 10mA of load current will apply.
Example:
The amplifier sourcing 10V into a meter with 100Ω input impedance will result
in 100mA current being drawn.
Therefore, a reduction in output of 10mV will occur
