Solar Thermal Exploration Kit, Explore variables such as box color, light intensity, tube design, rate of water pumping, and amount of time it takes to heat water. Includes some basic information on solar water heating systems and how they work
DC Power supply, can be used as a constant voltage source with current limiting or as a constant current source with voltage limiting, power: 100W, Stability under full load </= 0,01% + 5 mV, </= 0,2% + 5 mA, 3 mA, Display: 2 x 3 digit LED, Terminals: 4 mm
Low voltage power supply with four outputs and four independent and adjustable DC voltages. The DC voltages are stabilized, regulated, floating, and galvanically isolated from one another, in addition to being short circuit proof and secure from external voltages.
QuadraSource* Power Supply, Features an easy-to-use, full programmable interface for setting voltage, current or timer control with each parameter displayed in real-time, Programs may be paused or resumed at any point
High Torque Generator with Wires, produces lower voltage but higher current for a given rotor speed, has 4-foot leads with shrink-wrap reinforced soldering, with 2 mm driveshaft as the standard Wind Turbine Generator, for load devices with higher current draw, such as water pump
Transformer with Rectifier, Extra low-voltage power supply with overload protection in plastic housing, four switchable stages, Output voltage: 3/6/9/12V-3A, Maximum load: 3A, Terminals: 4mm safety sockets, Dimensions: 210x170x90 mm3, Weight: 2.6kg
With 30V/20A Max output features remote control for output Voltage/Current and On/Off, dual 3-Digit LED displays, overload, over-temperature, and short circuit protection, and thermostatic controlled fan.
