Description
Technical Parameters
| Parameter | Specification |
|---|---|
| Input Voltage | 125 VDC nominal (range 100–150 VDC); 24 VDC compatible with external adapter |
| Output Rails | +5 VDC / 12A (main logic), ±15 VDC / 2.5A (each rail, analog circuits) |
| Isolation | Full isolation (1.5kV input‑to‑output, 2.0kV output‑to‑ground) |
| Protection | Overcurrent protection (fixed), short‑circuit protection, transient suppression (4kV), reverse polarity protection, input undervoltage lockout |
| Regulation | Load regulation: ±0.3%; Line regulation: ±0.15%; Ripple: < 25mVpp (+5V), < 15mVpp (±15V) |
| Monitoring | 4 analog feedback channels (voltage and current monitoring for each output rail); 3 digital fault outputs (relay, 24V/1A) for system faults |
| Supervisory Control | Onboard microcontroller for diagnostic reporting and system health monitoring; communicates with main CPU via backplane |
| Operating Temperature | –25°C to +60°C |
| Form Factor | 6U × 6HP (30mm) – requires 1.5 slots |
| Backplane Connector | Standard VME 96‑pin P1 + reinforced 60‑pin P2 |
| Status LEDs | 6 indicators: +5V OK (green), +15V OK (green), –15V OK (green), SYSTEM OK (green), FAULT (red), COMM ACTIVE (white) |
| Certifications | CE, UL 508 (non‑hazardous locations only) |
| Efficiency | ~84% at full load |
Critical note: The DS3800NSCC is a supervisory control power interface designed for integrated power management. It is physically wider (6HP) than standard 4HP boards and requires 1.5 adjacent slots. Hot‑swapping is not supported.
Key Features & Advantages
-
Supervisory Control – Onboard microcontroller provides diagnostic reporting and system health monitoring.
-
Comprehensive Monitoring – Four analog channels provide voltage and current telemetry for all outputs.
-
Three Fault Relays – Separate fault indication for system faults.
-
Full Isolation – 1.5kV isolation protects sensitive circuits.
-
Backplane Communication – Communicates system status to the main CPU.
Typical Application Cases
-
Main Control Cabinets – Provides power with integrated system monitoring.
-
Advanced I/O Racks – Powers racks requiring supervisory power management.
-
System Integration Projects – Used when integrated power reporting is required.
Selection Guidelines & Precautions
-
Application Verification – Designed for integrated power management with supervisory control.
-
Physical Compatibility – 6HP wide, requires 1.5 adjacent slots.
-
Backplane Compatibility – Uses P1 and P2. If backplane lacks P2, supervisory features unavailable.
-
Thermal Derating – Full output to 50°C; derate to 90% at 50–55°C, 80% at 55–60°C.
-
Spare Sourcing – Production ended in 2010. Request test report verifying outputs and supervisory functions. Inspect for capacitor bulging or discoloration.
