FAQ
Can I use this power supply for both 12V and 24V devices simultaneously?
No, this is a selectable power supply that operates in either 12V mode (8A max) or 24V mode (4A max), but not both simultaneously. You need to configure it for one voltage before use and change the output fuse accordingly (F8A for 12V, F4A for 24V).
How do the switchable outputs work?
The 8-way fuse board includes relay-controlled outputs that can be individually switched on or off. The relay can be triggered using normally closed (NC), normally open (NO), positive, or negative signals between 5-24V DC, allowing each output to hold or drop power as required.
What size batteries can I install for backup power?
The enclosure can accommodate 2x 12V 7Ah batteries maximum. The integrated charger provides up to 0.7A charging current and includes protection against over-charge and over-discharge to maintain battery health.
What accessories are included with the power supply?
The unit comes with essential accessories including fuses (8A, 4A, 3A, 2A), 1x PG11 cable gland, 2x M20 rubber grommets, 4x plastic sticky feet, battery connection leads, and a battery jumper lead.
What protection features are built into this power supply?
The unit includes comprehensive protection against over-current, over-load, over-charge, and over-discharge. It also features tamper detection on both front and rear panels, mains/fault LED indicators, and individual fuse protection for each output.
