Electronic Loads with multiple modes of operation

The FK-series electronic DC loads offer four modes of operation: Constant current, constant resistance, constant voltage and constant power. Within the multiple mode operation, these compact multi-functional DC load units serve an extensive range of applications from testing a switching power supply or other electronic devices to developing a solar battery or other energy sources. Especially in the constant voltage mode, the FK-Series comes with the ÐR function which is proven effective in testing battery chargers.

All setting of the electronic load are controlled through a CPU based digital control circuit, there by attaining fine resolution and accurate and repeatability. Up to eight units of the same model of loads or boosters can be operated, in parallel master-slave-mode. The signals for the units for this mode of operation can be controlled an monitored by the master unit alone, with displays the current setting, resistance setting, and also the total current and total power.

Features:

Compact 1/4" rack size, but large load power of 200 W.
Four modes of operation: constant current, constant resistance, constant voltage and constant power.
Internal resistance in constant voltage mode changeable by the ÐR function.
Low minimum operating voltage.
Switching three kinds of settings in memory possible.
Digital voltmeter, ammeter and wattmeter and bar-graph wattmeter.
Control and reading by a personal computer in an optional configuration.
Current can be supplied to the load such as capacitance input type electronic equipment with rush and current flow.

Programmer for FK-Series (TC 911 B)

System Structure:

The TC 911 B Programmer has an Interface port for GP-IB and RS 232 C, allowing both-way communications between an FK Series Electronic Resistance Load an a computer through a Task-Bus cable. Up to sixteen unit of FK-Series devices can be controlled with a single unit of TC 911 B. The Task-Bus cable is a 20-core ribbon cable with connectors for ready hooking up of the devices.

Features:

For FK-Series settings of all operation parameters and reading back of the measured voltage, current, and power and the set parameter values can be made with the computer.

The set values and measured values can be handled in terms of real numbers by the computer software.

The signal cables are connected on side panels of the devices in order not to be in the way when you access the rear panels of the devices.

A space for installing the TC 911 B is secured at a right-hand corner of the rack, thereby making the rack mount looks neat.
