Note(注释):
1.Prodigit has not fully transitioned to lead-free solder assembly at this moment；However, most of the
components used are RoHS compliant.
(此刻，Prodigit 并非完全过渡到无铅焊料组装；但是大部份的元器件一至于RoHS的规定。)
2. The product is labeled with an environment-friendly usage period in years.
The marked period is assumed under the operating environment specified in the product specifications.
(产品标注了环境友好的使用期限制(年)。所标注的环境使用期限假定是在此产品定义的使用环境之下。)

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.
