Electricity Trainer KL-100     Features Ideal for electricity circuit experiments and design exercises. Integrated training system, with complete curriculum. Built-in power supplies and test facilities for easy and efficient experimentation. Large breadboard for circuit design and prototyping. 11 experiment modules form basis for nearly 60 fully documented experiments. Main units and experiment modules also available separately for economical construction of class sets. The KL-100 Electricity Trainer is a comprehensive and self-contained system suitable for tuition and experimentation with a range of electricity circuits.   KL-100 Main Unit The main unit incorporates all necessary equipment for use with the eleven plug-on training modules. Power supply, function generator, and analogue and digital meters are all built-in. The DC power supply provides fixed ±5V and ±12V at 0.3A, a variable ±3V ~ ±18V at 1A, and a transformer provides a 9V~0V~9V AC output at up to 500mA. The function generator offers sine, square, and triangle waveforms at frequencies from 10Hz ~ 100kHz in 4 ranges. The main unit is also supplied with a removable 1680 tie point universal breadboard for general experimentation and prototyping. KL-100 Experiment Modules Eleven modules form the basis for the 59 experiments detailed in the comprehensive experiment manual. Each module contains the experiment circuit which is clearly illustrated by a cicuit diagram on its top panel. Switch faults are also incorporated into the modules for simulating fault situations.   KL-13001 Basic Electricity Experiment Module KL-13002 Magnetism Introduction Experiment Module KL-13003 Magnetic Field Experiment Module KL-13004 Ampere's Rule Experiment Module KL-13005 Fleming's Rule Experiment Module KL-13006 Induction Experiment Module KL-13007 Fundamental Electronic Circuits Experiment Module KL-13008 Basic Electronic Circuits (1) Experiment Module KL-13009 Basic Electronic Circuits (2) Experiment Module KL-13010 Special Electronic Components Experiment Module KL-13011 Oscillator Characteristics & Applications Experiment Module The full list of experiments performed using the above modules and detailed in the experiment manual are: Basic Electricity Experiments DC voltage measurement Using an ohmmeter Resister characteristics DC current measurement Ohm's law Power in DC ciruits Series-parallel circuits and Kirchhoff's law Superposition, Thevenin's and Norton's theorems Maximum power transfer theorem DC RC circuits and transient phenomena AC voltage measurement AC current measurement AC RC circuits AC RL circuits AC RLC circuits Power in AC circuits Transformer characteristics Series resonant circuits Parallel resonant circuits LC filters Magnetism Experiments Magnetic devices Magnetic fields Drawing magnetic curves Magnetic field strength Lenz's and Faraday's laws Ampere's rule Fleming's rule Self induction Mutual induction Magnetic flux detection Fundamental Electronic Circuits Experiments Diode characteristics Rectifier circuits Filter circuits Zener diode characteristics LED characteristics Transister characteristics Multimeter functions FET characteristics SCR characteristics UJT characteristics Basic Electronic Circuits Experiments Simple amplifier Complimentary amplifier Voltage regulator Push-pull amplifier Wheatstone bridge Dimmer circuit Multistage cascading amplifier Relay characteristics Touch controlled switch Control Applications Experiments CDS characteristics Light controlled circuit Thermister characteristics Temperature controlled circuit Sound controlled circuit Oscillator Characteristics & Applications Experiments Blocking oscillator Electronic birdcall circuit Astable multivibrator LED flasher circuit LC resonant circuit Specifications KL-100 Main Unit Fixed DC Power Supply Voltage range: +5V, -5V, +12V and -12V Maximum current output: 300mA Output overload protection Variable DC Power Supply Voltage range: +3V ~ +18V, -3V ~ -18V Maximum current output: 1A Output overload protection AC Power Supply Voltage range: 9V~0V~9V Maximum current output: 500mA Output overload protection Function Generator Four frequency ranges: 10Hz to 100Hz 100Hz to 1KHz 1KHz to 10KHz 10KHz to 100KHz Waveforms: Sine, Square, Triangle Accuracy: ±5% of full scale value Output impedance: 50W Output voltage: ³18Vp-p (open-loop); ³9Vp-p (with 50W load) 3½ Digit Digital Meter DC Voltage range: 2V, 200V DC Voltage accuracy: ±0.3% of reading + 1 digit DC current range: 200µA, 2000mA DC current accuracy: ±0.5% of reading + 1 digit Analogue Meters AC current: 0 ~ 100mA ~ 1A AC Voltage: 0 ~ 15V DC current: 0 ~ 100mA ~ 1A DC Voltage: 0 ~ 20V Speaker 8W, 0.25W speaker with driver circuit Variable Resistors 1kW, 0.25W variable resistor with 3 terminals (A, B, C) 10kW, 0.25W variable resistor with 3 terminals (A, B, C) 100kW, 0.25W variable resistor with 3 terminals (A, B, C) 1MW, 0.25W variable resistor with 3 terminals (A, B, C) Removable Solderless Breadboard 1680 interconnected tie points, accepting all DIP devices, components with leads and solid wires of AWG #22-30 (0.3mm to 0.8mm) Accessories Power lead, connecting leads, fuse, dust cover, and user manual Power Supply 110/220V AC ±10% 50/60Hz Physical Characteristics Dimensions: 400mm (width), 300mm (depth), 130mm (height) Weight: 5.8kg
