The Keysight 6050A and 6051A Multiple Input Electronic Load Mainframes are used for design, manufacturing, and evaluation of dc power supplies, batteries, and power components. The 6050A and 6051A Multiple Input Electronic Load Mainframes are used for design, manufacturing, and evaluation of dc power supplies, batteries, and power components. Other applications include use as a power circuit breaker or crowbar, high-current function or pulse generator, fuel-cell and photovoltaic cell test, and de-energizing superconducting magnets.
The mainframe contains six (two) slots for load modules. Load modules occupy either 1 or 2 slots, depending on the power rating of the module. The mainframe can dissipate up to 300 watts per slot, to a total of 1800 (600) watts for a fully loaded mainframe. An individual module may have either 1 or 2 channels, each of which has its own channel number. Each module contains its own input connectors. The mainframe contains a processor, GPIB connector and interface circuits, trigger circuits, front-panel keypad and display, and other circuits common to all the load modules.
Each module can operate independently in constant current (CC) mode, constant voltage (CV) mode, or constant resistance (CR) mode. In addition, each input can be turned on or off (open circuit) or short circuited. Features include built-in GPIB interface and built-in pulse generator, both standard. Pulse mode allows dynamic testing of power supplies and components, without giving the device under test time to heat up. The flexible pulse mode provides six triggering methods, allowing synchronization with a wide variety of events. A Save/Recall feature allows you to save up to 7 complete instrument setups, one of which can be saved in non-volatile memory so that it is recalled automatically at poweron. Also standard is GPIB readback of actual input voltage and current, and extensive protection and status reporting capability.
