New Circuit Design Trainers

New PB-503A and PB-505A

Global Specialties releases an updated version of its classic Circuit Design Trainers. The new PB-503A and PB-505A now feature a function generator with digital display for accurate settings. Now you can precisely dial in your frequency to the nearest 0.1 Hz.

The generator provides a 100 kHz signal in two ranges, and outputs 10 Vp-p into a 600 Ω load (20 Vp-p into an open circuit). Take your choice from sine, square, triangle, and TTL waveforms.

Ideal for classroom usage, the PB-503A and PB-505A combine the essential elements of a bench top lab including a power supply, function generator, and breadboard replacing a more expensive individual setup.

Both new units equipped with:

Triple output DC power supplies
100 kHz digital function generator
Removable breadboard for multiple users
Two digital pulsers
High and low buffered logic indicators
8 Channel logic switches
2 SPDT switches
16 LEDs for logic indicators
2 BNC connectors
2 Potentiometers (1 kΩ and 10Ω)
Speaker
3 Year Warranty

These units have switchable input so they can work in both 120 VAC and 240 VAC environments. The also feature removable breadboards making them ideal for group projects in class where each student can prepare their own circuit.

Additional features on the PB-505A:

AC power supply (12.6 VAC center-tapped)
Logic Probe
BCD to 7-Segment Displays
