EEL1500-2 User Manual V1.0
The High Voltage Amplier (HVA) model EEL1500-2 is specically designed
for the MacroFiberComposite™ (MFC).
The EEL1500-2 is a 2-channel, high speed, 55 Watt High Voltage Amplier
capable of generating a -500 to +1500Vpp output @ +/-50mA with a large
signal bandwidth greater than 150kHz at -3db, no load per channel. The
xed amplication for a signal applied to the Control Input to generate High
Voltage output is 200.
With OFFSET switch OFF, a -2.5V to +7.5V input (AC or DC) generates a
-500V to +1500V output.
With the OFFSET switch ON a 500V oset is activated. The Control Input
accepts in this mode -5V to +5V (AC or DC) symmetric input. This
generates -500V output at -5V input, +500V output at 0V input and
+1500V at +5V input.
There are three LED indicators for each channel on the front panel,
signaling the following conditions. The two channels are identied as
AMPLIFIER 1 and AMPLIFIER 2.
1. When the unit is powered on, the LED POWER ON illuminates,
2. When the high voltage is on (enabled), the LED HIGH VOLTAGE
illuminates,
3. If high voltage output goes into an Out-Of-Regulation condition (high
voltage output doesn’t match the input), the LED OUT OF REGULATION
illuminates.
The high voltage is turned ON by providing a TTL LOW to the HIGH
VOLTAGE ENABLE BNC on the rear panel, or by plugging the shorting cap to
the HIGH VOLTAGE ENABLE BNC for each channel.
A DYNAMIC ADJUSTMENT1 turn potentiometer is provided on the front
panel to adjust for optimum square wave shape with varying capacitive
loads.
Two monitors are provided for each channel. The VOLTAGE MONITOR BNC
represents a 1:200 representation of the HIGH VOLTAGE OUTPUT. The
CURRENT MONITOR BNC represents a 1V to 5mA representation of the
CURRENT being drawn from the amplier.
The EEL1500-2 comes in a 19” rack, 2U case.
