33501 Series Operation Manual 1-1
Chapter 1 Introduction
1-1. General description
The 33501 Series Electronic Load is designed to test, evaluation and burn-in of DC power
supplies and batteries. The 335011 Series electronic load can be operated for manual and
GPIB operation. The power contour of 33501 1800 Watts Electronic Load is shown in Fig 1-
1.1~1-1.5, it has an input from 0-360A, and 0 -60V current and voltage operating range
respectively. The power contour of 33501 series. The prodigit 33501 Series high power
electronic Load can be controlled locally at the front panel or remotely via computer over the
GPIB/RS-232C. Current (CC) mode, Constant Resistance (CR) mode, and Constant Voltage
(CV) mode. and Constant Power ( CP ) mode. The wide range dynamic load with
independent rise and fall current slew rate and analog programming input with arbitrary
wave-form input is available in Constant Current mode.
