GE DS3815PCLA
Product Name: GE IS200 / DS3815 Power Supply Board
Product Overview: Based on available supplier documentation, the DS3815PCLA is a power supply module in GE’s Speedtronic IS200 / DS3815 family, configured for 48 VDC input with enhanced output filtering. (Note: documentation varies across sources — some reference it as a driver CPU board or digital output module; the PCLA variant is most consistently identified as a 48V PSU board with enhanced filtering.)
Detailed content
Technical Specifications (based on DS3815PCLA1D1D reference data):
- Manufacturer: General Electric
- Series: Mark VI / IS200 Speedtronic
- Input Voltage: 48 VDC nominal (accepts 48 VDC only, per PCLA variant definition)
- Output Rails: 48 VDC, 24 VDC, and 5 VDC
- Enhanced Filtering: Additional LC filter stages on all three output rails, reducing ripple — 5V logic rail ripple drops from <50 mV to <20 mV peak-to-peak
- Temperature Rating: Extended to -40 to +75°C (enhanced vs. standard)
- Conformal Coating: Present (ruggedized variants)
Key Differentiators:
- The PCLA adds enhanced output filtering compared to the standard PCBA variant
- Critical for sensitive analog measurements (thermocouples, vibration probes, 4-20mA transmitters) in the same rack
- Solves high-frequency noise coupling issues that can cause jitter in thermocouple inputs
Application Scenarios: Provides regulated power within Mark VI Speedtronic turbine control racks, particularly important in installations with sensitive analog measurement equipment.
Installation & Usage Notes: Not interchangeable with PAAA variant (which accepts 125 VDC or 240 VAC). Choose based on plant’s available DC supply and noise sensitivity requirements.
