The PLZ-U Series Electronic Load is a compact, high-performance, multi-channel electronic load unit that has three operation modes: CC (constant current), CR (constant resistance), and CV (constant voltage). The PLZ-U consists of a frame and load units. Load units are inserted into the frame (control section) for operation. The PLZ-30F and PLZ-50F Frames can accommodate up to 3 channels and 5 channels of load units, respectively. The current capacity or power capacity can be increased through a parallel operation of load units. The load units can be combined to produce a power capacity from 75W to 750W (when five PLZ150Us are installed into the PLZ-50F). In addition to high-speed response and highly precise pre-set resolution, various functions are provided including the soft start function, variable slew rates, switching function, ABC pre-set memories, four set-up memories, and sequence function. GPIB and RS232C as fitted as standard.
Slew rate of 2.4 A/?s in the rising and falling edges in CC mode (PLZ150U)
Built-in three ranges; voltmeter, ammeter, and wattmeter functions that provide readings of up to five digits
The current slew rate can be changed continuously in constant current and constant resistance modes.
Supports 0-V input - an indispensable feature for testing single cell fuel cells.
Individual units (channels) can operate either independently or in synchronisation.
Up to five load units of the same model can be operated in parallel.
Up to three values can be stored in memory for each most frequently used operation mode and range.
Equipped with various types of protection circuits (over voltage protection, over current protection, over power protection, over heat protection, under voltage protection, and reverse connection protection).
Supports the GPIB and RS-232C interfaces as standard.
External control is available to turn on or off the output.
