PEL-60-60-10 - Physical Instruments

TRANSIENT MODE
AMETEK’s Programmable Electronic Load can facilitate testing sources and load simulation through the use
of its internal transient generator. This transient capability allows the user to determine operating specifications
for instruments such as a power supply. This capability also allows for pulse-charging a battery and for
simulating battery drain.
LOCAL TRANSIENT OPERATION
LCL Operation:
From keypad, press the “Utility/Local” key. Use and “Enter” keys to select
the following submenus:
UTILITY/LOCAL→GPIB→TRANSIENT MODE→CONTINUOUS
→STEPPING
→PULSE
→TOGGLE
CONTINUOUS MODE
In continuous mode, the PEL input switches between 2 user defined levels; main and transient. The duty cycle
and frequency is user defined.

Typical application: Testing the Load Regulation (Effect) of a power Supply, defined as the voltage change in
dc output due to a change in load current from minimal resistance (closed circuit) to maximum resistance (open
circuit). The PEL Load can be programmed to switch between any two current levels.
LCL Operation:
• From keypad select operating mode (CC, CV, CR, CP)
• Select transient operation for continuous mode.
• Set MAIN and TRANSIENT levels by pressing the “MAIN” and “TRANS” keys.
• Set the duty cycle and frequency by pressing the “Function” key and selecting the DUTY
and FREQUENCY submenus. The duty cycle can be set from 2% to 98% and the frequency
from 0.1Hz to 20 KHz.
• To begin the transient operation, turn on the input and press the “TR ON/OFF. The LCD
will display “ON TR”.
