BK Precision 8500B Series - 8.2.2 Current Limit (A-LIMIT); 8.2.3 Power Limit (P-LIMIT); 8.2.4 Timer Function

Conguration Menu 71
8.2.2 A-LIMIT
A-Limit limits the maximum current that can ow through the load. When the current exceeds the set
threshold, the load shuts down to prevent damage to the load or the power source. OCP is crucial for
preventing excessive current that could lead to overheating, component failure, or unsafe conditions.
A delay can be introduced to extend the time between crossing the current threshold and the subsequent
disabling of the input.
When Overcurrent Protection (OCP) is triggered, the input will be temporarily
disabled. Once the OCP is cleared, the input will automatically re-enable. It is
crucial to adjust the power source before clearing OCP to prevent its reactivation.
8.2.3 P-LIMIT
The P-Limit function constrains the maximum power dissipation of the load. If the power surpasses the
dened threshold, the load initiates a shutdown to safeguard against potential damage to both the load
and the power source. OPP (Over Power Protection) is essential for averting excessive power, which
could otherwise result in overheating, component failure, or unsafe operating conditions.
A delay can be introduced to extend the time between crossing the current threshold and the subsequent
disabling of the input.
When Overpower Protection (OPP) is triggered, the input will be temporarily
disabled. Once the OPP is cleared, the input will automatically re-enable. It is
crucial to adjust the power source before clearing OPP to prevent its reactivation.
8.2.4 TIMER
The timer setting empowers users to establish a precise duration or time limit for the load operation.
This functionality facilitates automated control over the load’s on/o cycles, oering convenient timing
capabilities for both testing and operational applications.
By utilizing the timer setting, users can precisely dene the duration of the load operation in seconds.
When the predetermined time limit is reached, the load can automatically switch o, concluding the
intended testing cycle. This feature proves especially valuable in scenarios such as endurance tests,
assessing battery life, or conducting evaluations based on time constraints.
