Operating Modes The devices have constantcurrent and constant-resistance operating modes in both static and dynamic operation. If fitted with an RS-232 or GPIB interface, softwarecontrolled constant power control is possible. The manual setting of the load values takes place via two precise ten-turn potentiometers. Switch from value A to value B by a keystroke. PL1006 2) Rise and fall times are defined from 10 ... 90 % and 90 ... 10 % of the maximum current. (Constant current operation, tolerance +/- 20 %). Dynamic Operation In dynamic mode the inbuilt modulator performs the switch between the setpoints A and B. For each load level it is possible to set a corresponding pulse duration of 0.5 ms ... 500 milliseconds. In addition, pulse-pause ratios can be varied within broad time range. Switching between the two load levels can also be via the analogue I/O interface at all levels between 3 V and 30 V.

Depending on the model the devices have temporary overload capacity. The level and duration of the possible overload depends on the operating temperature of the power stage. The device can also be used for significantly higher power tasks. GTC 8
The Electronic Load RS-232 Interface (Option PL01) The RS-232 interface is the most economical option for controlling devices by PC. It also includes the system bus interface which allows multichannel systems to be constructed. GPIB + RS-232 interfaces (Option PL02) Combined GPIB + RS-232 interface + system bus interface External LAN-RS232 Adapter (Option PL04) Enabled the device to be controlled via LAN interface. Analog I/O Interface Standard Analog I/O Interface with 0 ... 10V level for: Input voltage Load current Power consumption Nominal current Master-Slave circuit The control of the load current can be via an analog signal with optionally 0 ... 5 V or 0 ... 10 V. Requires PL01 or PL02. Software Tools The H&H Homepage has a program library for Windows with the following applications: Load control via PC Programming of custom load profiles Recording of current limitation characteristics Endurance test with memory function for voltage and current Battery testing with recording of discharge curves LabVIEW driver The Analog I/O Interface also has the following logical inputs and outputs: “Overload“ status for the overload display Trigger output during dynamic operation Trigger input for external control of the dynamic load change Control input for battery test Control Input for external load activation Sense terminals (for 60V and 120 V models) Factory Calibration Certificate (Option FCC-PLxx) A Factory Calibration Certificate (FCC) can be supplied with the devices. The FCC meets the requirements according to DIN EN ISO 9000ff. This calibration certificate documents the traceability to national standards to illustrate the physical device in accordance with the international System of Units (SI). The recommended calibration interval is 1 year. GTC Application Notes ZS PL H&H ZSLC Water-cooled ZSLV Low Voltage PMLI Multi-channel ZSAC AC NL Source-Sink Interfaces Optional interfaces are an RS- 232 and a combined GPIB + RS- 232 interface. The interfaces enable all settings functions including comprehensive dynamic settings incl. programmable rise and fall times. There is also a measurement function for input voltage and load current. All interfaces are electrically isolated from the load input to prevent earth loops forming with the test structures. Programming takes place in SCPI syntax. Configuration of a Multichannel System For control of additional devices via the GPIB or RS-232 interface of the primary device, any number of devices can be connected via the system bus interface (Option PL01 in all other devices). Despite the shared interface, the devices are electrically isolated from one another and can be operated with potential differences of up to 125 V. Accessories Software 9
