The modules protect your system's components and wiring against overcurrents and short circuits, preventing costly failures and system downtime. Furthermore, these devices ensure the safety and functionality of your power supplies.
In short, these devices improve system reliability while saving costs and cabinet space.
PISA-M fuses are by far the smallest 4-channel electronic fuses on the market. All models are only 22.5 mm wide, making them compatible with any system.
The PISA-M series offers several models: those with four fixed-current outputs (2, 4, 6, and 8A) and the PISA-M4ADJ model, which allows you to adjust each of the four outputs to 1, 2, 3, 6, or 8 amps. In all models, each channel is independent, so if one channel experiences an overload, the others continue to function.
These electronic fuses are suitable for 12V and 24V power supplies and offer a choice of fast or slower protection. Tripped channels can be reset using the front panel buttons or remotely via a signal. They can withstand input surges of up to 1500V and are Class III rated.
An additional negative terminal is included for easier load connection; if the power supply draws more than 20 amps, this negative terminal must be connected directly to the loads.
The unit also protects itself if it detects a voltage drop (possibly due to an overload of connected loads, even if none exceed the maximum current). Outputs start sequentially with a 100ms phase shift.
An intelligent system compares input and output current, and the unit protects itself if a problem is detected. The programmable model features a simple digital protocol for easy configuration and monitoring.
Other features include quick-connect (plug and play) connectors on the front panel for fast, tool-free installation. The multi-colored LEDs display the status of each output channel in real time. Each channel is equipped with a button that can be used to turn the outputs on, off, and reset.
