PEL-60-60-10 - Physical Instruments

THREE: LOCAL OPERATION
INTRODUCTION
The programming electronic load provides powerful control capabilities, which consist of four operating modes
CV/CC/CR/CP. To complement and enhance these features, a Transient mode is provided to simulate transient
conditions. The Transient operation provides three programmable features that can be set by the user, Transient
frequency, Transient duty cycle, and Transient slew rate. These features can help the user to control the PEL more
efficiently and precisely and provide a comprehensive power source test.
The programming electronic load provides additional functions and capabilities, such as 99 point step programming,
255 recording points, and clock. For battery testing, we provide the “C” operand to help user in testing battery
parameters without troublesome calculations.
The wide operating modes and specifications and flexibility of the electronic load enable the user to control different
levels of power source. Programmable OVP, OCP, OPP protection features are provided to protect the electronic load
in any load conditions. Refer to the specifications to check the maximum input current, voltage, and power range in
order to safely test and obtain the best results.
VOLTAGE AND CURRENT METERING INFORMATION
The programming electronic load uses a DAC with a 12-bit resolution in the metering system and is active once the
unit is turn on. With sophisticated control circuits, the load can measure full-scale input voltages and currents with
Auto-Scaling capability. For example, when low voltages levels are applied, the display's decimal point will move to
accurately display the lower value. The same is true for the larger input values, the decimal will move to accurately
display the higher value. Refer to the Specifications for more programming and read back accuracy information.
