Ground loops are broken. Troubleshooting is simplified. Input is protected by transorb diodes. The converter can withstand very high transient voltages without damage. Input can withstand up to 120 volts without damage.
Outputs are current limited.
Outputs can withstand short circuits without damage. Outputs are diode protected. Output can withstand high positive voltages without damage. Output circuits are socketed. High negative voltages on outputs may damage the output circuit.
