Sam Electronics AG 6022-SD102-001 Rev-A00 230VAC Power Supply

Description

3. Key Technical Specifications

6022-SD102-001

4. Product Introduction

The Sam Electronics AG 6022-SD102-001 Rev-A00 is a 230VAC primary-switched power supply module designed specifically for marine automation systems, including legacy Sam Electronics DCS platforms and certain Siemens Ship Automation racks. This unit provides isolated 24VDC power to I/O modules, CPUs, and communication interfaces.

The Rev-A00 revision includes improved transient suppression over earlier non-revision boards, making it more resilient to generator startup spikes and thruster harmonics. Field experience shows these units typically run 50,000+ hours before capacitor degradation. For vessels running Sam Electronics 6000-series or 7000-series systems, this remains the drop-in replacement. No modification to existing backplane wiring or DIN rail positioning required.

5. Installation & Configuration Guide

Total estimated time for trained technician: 25 minutes

Stage 1: Pre-Installation Preparation (5 minutes)

⚠️ Safety First: Notify bridge/engine control room. Isolate the 230VAC supply breaker. Lock-out/tag-out (LOTO). Wait 5 minutes for internal capacitors to discharge. Verify zero voltage at input terminals with a multimeter.

Tools Required:

• ESD wrist strap (grounded to ship’s ground or rack chassis)
• Fluke 115 or equivalent true-RMS multimeter
• 3mm flathead screwdriver (for cage-clamp terminals)
• Wire labels (Brother P-touch or similar)
• Smartphone for photos

Data Backup & Documentation:

• Photograph all wiring connections before loosening any terminal.
• Document which downstream devices receive power from this module (use a marker to label each wire: “AI1 rack,” “CPU rack,” etc.).
• Note any custom output voltage adjustments (some Rev-A00 units have a hidden trim pot under the front label).

Stage 2: Removing the Old Module (5 minutes)

1. Remove the front protective cover (two Phillips screws on Rev-A00).
2. Photograph LED states while powered down (if possible — indicates pre-failure condition).
3. Label every wire using the photo reference. Do not trust color coding alone.
4. Loosen cage-clamp screws fully. Remove wires one at a time.
5. Release DIN rail locking clip (push upward with flathead screwdriver).
6. Slide the module upward off the DIN rail. Do not pry.

⚠️ Keep the old module in an ESD bag for 30 days after replacement. Some vessels require it for warranty claims.

Stage 3: Installing the New Module (8 minutes)

1. ESD prep: Grounded wrist strap. Work on ESD mat.
2. Verify model match: 6022-SD102-001 Rev-A00. Rev-B00 or Rev-C00 are NOT pin-compatible.
3. Inspect the new unit: No bent pins, no bulging capacitors (visually check the vent crosses on top).
4. Mount onto DIN rail: Tilt top in first, then push bottom until locking clip clicks audibly.
5. Critical — Voltage selector check: Rev-A00 has an internal jumper for 230VAC vs. 115VAC. Confirm it’s set to 230VAC (factory default, but verify). Open the small access panel on the side.
6. Reconnect wiring in reverse of removal. Torque cage-clamp screws to 0.5 Nm (fingertight plus 1/4 turn).
7. Double-check polarity: L (live), N (neutral), ⏚ (ground) on input side. Output side: +24V and 0V.

Self-Checklist:

• Jumper set to 230VAC
• No stray wire strands outside terminals
• DIN rail clip locked
• All wire labels match the photo

Stage 4: Power-On & Testing (7 minutes)

Pre-Power Check:

• Multimeter on resistance mode (200kΩ scale). Measure between L and N inputs: should read >100kΩ (not shorted).
• Measure between +24V output and ground: >10kΩ minimum.

Power-On Steps:

1. Close the 230VAC breaker.
2. Observe LEDs:
   • Green Input OK = AC present.
   • Green Output OK = 24VDC stable.
   • Red Fault = Overload or short circuit. Power off immediately.
3. Measure output voltage at terminals: 24.0V ±0.5V (no load).
4. Connect load (reconnect downstream devices one at a time). Monitor voltage droop.
5. Run for 10 minutes. Measure case temperature with thermal camera or back of hand. Should be warm but not hot (>70°C is abnormal).

⚠️ Troubleshooting Notes:

• Red Fault LED after power-on: Disconnect all output loads. If fault clears, one downstream device has a short. Reconnect one at a time to find it.
• No output, Input LED off: Check breaker, wiring, and internal fuse (non-user replaceable on Rev-A00).
• Output voltage below 22V: Possible overload or failing capacitors. Measure current draw. Should not exceed 5A continuous.

6. Frequently Asked Questions (FAQ)

Q1: Can I hot-swap this 6022-SD102-001 while the rack is powered?
A: Absolutely not. This is not a redundant hot-swap design. Removing or inserting this module with 230VAC applied can arc across the terminals, damage the backplane, and injure you. Kill the breaker first. I’ve seen a ship’s electrician try this — it welded the terminal block and took out two adjacent I/O modules.

Q2: Is this model obsolete? Why is your price lower than Sam Electronics list?
A: Yes, Sam Electronics AG discontinued the 6022-SD102 series in 2018 (official obsolescence notice SAM-OBS-2018-042). Our units are new original surplus — excess inventory from decommissioned shipbuilding projects or canceled orders. Lower price reflects the absence of factory warranty and no technical support from Sam Electronics. We provide our own 1-year warranty and pre-shipment testing.

Q3: What’s the direct replacement if you’re out of stock?
A: Sam Electronics recommends the 6022-SD110-002 (230VAC input, same form factor) but it requires a different backplane adapter (part #6022-ADP-01). Alternatively, a third-party solution like the PULS ML60.241 (60W) or ML100.241 (120W) can work, but you’ll need to fabricate a wiring adapter. The pinout is not identical. Contact us for a retrofit kit.

Q4: Will I lose my DCS configuration or PLC logic when I replace this power supply?
A: No. This is a pure power module — it has no memory, no firmware, and no configuration. The CPU and I/O modules retain their logic. However, if your 24VDC distribution feeds a CPU’s backup battery charger, a prolonged power loss (>30 minutes) might drain the CPU’s internal capacitor backup. Keep the swap under 15 minutes to be safe.

Q5: Why does the Rev-A00 run hotter than newer Rev-C00 units I’ve seen?
A: Rev-A00 uses linear regulation for the auxiliary control circuitry, while Rev-C00 switched to fully switching topology. Linear regulators dissipate more heat — that’s normal. Surface temperature of 55-65°C at full load is within spec. If it exceeds 80°C or you smell burning, that’s a problem. Check for dust clogging the ventilation slots.

Q6: Can I use this on 115VAC shore power or 110VAC ship supply?
A: Not without modifying the internal jumper. The default position is 230VAC. Applying 115VAC with the jumper in 230VAC position will give you ~12VDC output — not enough to run your rack. To use 115VAC, open the side access panel, move the jumper to the 115V position, and relabel the unit clearly. We do not recommend this if the vessel ever returns to 230VAC.

Q7: Your listing says “New Original” but there’s no Sam Electronics hologram. Why?
A: Sam Electronics AG did not use holographic anti-counterfeit labels until 2015. The 6022-SD102-001 Rev-A00 predates that (manufacturing years 2006-2014). Authenticity verification is done via:

• PCB silk-screen matching factory Rev-A00 artwork
• Capacitor brand and date codes (Nippon Chemi-Con, 2009-2014 date stamps)
• Weight tolerance (±5g)
  We provide high-resolution PCB photos upon request for your verification.

Q8: Do you provide test reports before shipping?
A: Yes. Every unit goes through our 9-point SOP (see below). We run each 6022-SD102-001 on a test rack with a 150W resistive load for 2 hours, log output ripple, and verify overvoltage shutdown at 28.5V. A signed test report with serial number and measurements ships with the unit. Test videos available on request.
