Compliance & Standards Alignment
- Certified and recognized under major international standards, including UL, CSA, CE (EMC and LVD directives), UKCA, DNV, ABS, and Bureau Veritas (BV).
- Engineered to withstand high electromagnetic interference (EMI/RFI), severe mechanical vibration, and saline industrial atmospheres (Mil-Spec salt fog compliance tiers).
Technical Note: The specific alphanumeric suffix string (
-LN1CN1N) dictates factory-configured options regarding communication interfaces, auxiliary power supply voltage windows, and specialized software tracking features. Always cross-reference the exact style number on the unit’s nameplate with Basler’s technical manual prior to field replacement.
Storage & Asset Preservation Guidelines
- Store the module inside its original factory antistatic ESD packaging to protect sensitive microprocessor boards and internal power transistors from electrostatic damage.
- Maintain clean, dry warehouse storage environments with stable ambient temperatures and relative humidity kept below 60%.
- Avoid mechanical shocks, drops, or placing heavy weights on the unit to protect enclosure casing and terminal blocks.
Physical Installation Prerequisites
- Ensure that all prime mover controls, generator field lines, auxiliary power feeds, and high-voltage potential/current transformer (PT/CT) circuits are completely de-energized and locked out (LOTO) prior to installation or wiring.
- Mount the unit securely onto a clean panel surface inside a ventilated control cabinet, ensuring proper earth grounding via the designated chassis stud.
- Double-check all terminal wiring polarities—especially field output lines and sensing inputs—against the Basler instruction manual before applying control and power inputs.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this Basler excitation controller?
A: Automatic voltage regulators, industrial process controllers, and electrical regulating apparatus typically classify under HS code 9032.89 (Automatic regulating or controlling instruments and apparatus) or 8538.90. Confirm final categorization with your customs broker.
Q: Can the DECS-250 configuration be saved and transferred to a replacement unit?
A: Yes. Using Basler’s BESTCOMSPlus® PC software, operators can easily download, save, and upload complete configuration files and BESTLogicPlus programs, ensuring rapid swapping and minimal downtime during maintenance.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market availability, inventory source conditions, and global supply tiers; contact our technical sales desk for a formal, time-sensitive quotation.
