Compatible Replacement & Equivalent Models
If the SNAP-PS5 is discontinued, on long lead time, or outside budget, the following models may serve as functional equivalents depending on your rack configuration. Always verify electrical and mechanical compatibility before substitution.
- OPTO 22 SNAP-PS5U – Updated universal-input variant; direct form-fit-function replacement in most SNAP racks
- OPTO 22 SNAP-PS24 – 24 VDC output variant; suitable if your rack supports 24 V brain boards
- Phoenix Contact QUINT-PS/1AC/5DC/… – Third-party DIN-rail 5 VDC supply; requires external wiring adaptation
- Meanwell HDR-60-5 – Cost-effective DIN-rail 5 VDC supply; suitable for retrofit with custom bracket
Note: Third-party replacements require engineering review. Contact support@konmask.com for compatibility assessment.

System Compatibility
The SNAP-PS5 is compatible with the following OPTO 22 SNAP rack and brain board families:
- SNAP Racks: SNAP-B3M, SNAP-B6M, SNAP-B12M, SNAP-B16M, SNAP-B32M series
- Brain Boards: SNAP-PAC-EB1, SNAP-PAC-EB2, SNAP-ENET-S64, SNAP-ENET-D64, SNAP-LCE
- I/O Modules: All standard SNAP analog and digital I/O modules operating at 5 VDC logic
- Software: PAC Control, PAC Display, Node-RED SNAP PAC driver
Always cross-reference the SNAP rack datasheet to confirm power budget before adding modules.
Selection Guide
Use the following criteria to confirm the SNAP-PS5 is the right power supply for your application:
- Step 1 – Identify rack model: Confirm your SNAP rack part number (e.g., SNAP-B16M). Check the rack datasheet for required supply voltage (5 VDC = SNAP-PS5).
- Step 2 – Calculate power budget: Sum the current draw of all installed brain boards and I/O modules. Ensure total does not exceed SNAP-PS5 rated output current.
- Step 3 – Verify input voltage: SNAP-PS5 accepts 85–264 VAC universal input. Confirm your panel supply voltage is within range.
- Step 4 – Check mounting space: SNAP-PS5 occupies one slot in the SNAP rack. Confirm a slot is available.
- Step 5 – Confirm quantity: Large racks with high module counts may require two SNAP-PS5 units for redundancy or load sharing.

Replacement & Compatibility FAQ
Q: Can I use a standard DIN-rail 5 VDC supply instead of the SNAP-PS5?
A: Technically possible with wiring adaptation, but not recommended for production environments. The SNAP-PS5 is mechanically integrated into the rack and provides cleaner power distribution to all modules.
Q: Is the SNAP-PS5 compatible with SNAP-PAC-R1 or SNAP-PAC-R2 controllers?
A: SNAP-PAC-R series controllers have an integrated power supply and do not use the SNAP-PS5. The SNAP-PS5 is for SNAP expansion racks (SNAP-B series).
Q: What happens if the SNAP-PS5 fails?
A: All I/O modules and the brain board in that rack will lose power. The PAC controller will detect the loss and can be programmed to trigger a safe-state output. Replace the unit promptly to restore operation.
Q: Can two SNAP-PS5 units be used in one rack for redundancy?
A: Consult the specific rack datasheet. Some SNAP racks support dual power supply slots for load sharing; true hot-swap redundancy depends on rack model.
Q: Do you offer exchange or repair services for the SNAP-PS5?
A: Contact support@konmask.com to discuss repair, exchange, or consignment options.
