Technical Parameters & Selection Guide

Selection Guidelines: Calculate total system load including 20% future expansion margin. For redundant configurations, use N+1 architecture with load-sharing diodes. Ambient temperatures exceeding 50°C require forced-air cooling or uprated models. Battery sizing should target 4-hour runtime for critical loops, 30-minute minimum for non-essential circuits.

Extended Functions

Remote Monitoring Integration: Alarm relay contacts (Form C, 2A @ 30VDC) enable connection to building management systems or SCADA platforms. Configure for AC fail, DC fail, or battery low conditions to trigger automated notifications via Modbus RTU gateways.

Parallel Operation Capability: Install multiple 51198947-100H units with external ORing diodes for load sharing up to 40A total capacity. This architecture supports phased capacity expansion without system shutdown—ideal for growing automation networks.

Conformal Coating Option: Factory-applied acrylic coating (specify -CC suffix when ordering) provides protection against humidity, salt spray, and chemical vapors in coastal or corrosive environments, extending service life 3-5 years.

Delivery & Service Assurance

Lead Time: Standard units ship within 3-5 business days from regional distribution centers. Custom configurations (conformal coating, extended temperature range) require 2-3 weeks manufacturing lead time. Expedited delivery available for critical outage situations.

Warranty Coverage: Comprehensive 12-month warranty covers component defects, workmanship issues, and performance deviations from published specifications. Warranty includes advance replacement service to minimize downtime during RMA processing.

Technical Support: Access to application engineers for load calculations, battery sizing, and system integration guidance. Phone/email support available 8AM-6PM EST weekdays, with emergency hotline for production-down scenarios.

Documentation Package: Each module includes installation manual, wiring diagrams, dimensional drawings, and compliance certificates (UL, CE, CSA). CAD models and EPLAN macros available for download to accelerate panel design workflows.

Frequently Asked Questions

What battery chemistry works best with the 51198947-100H charging circuit?
Sealed lead-acid (SLA/VRLA) batteries in 12V or 24V configurations are recommended. The float voltage is factory-set to 27.6V (for 24V batteries) or 13.8V (for 12V batteries). Lithium batteries require external charge controllers due to different voltage profiles.

Can this power module operate in hazardous area classifications?
The standard 51198947-100H is rated for general industrial use (Class I, Division 2 when properly installed). For Division 1 or Zone 0/1 applications, install in purged enclosures or use intrinsically safe barriers on field wiring. Consult NEC Article 500 for specific installation requirements.

How do I calculate required battery capacity for my application?
Measure total DC load current, multiply by desired backup time in hours, then add 25% safety margin. Example: 5A load × 2 hours × 1.25 = 12.5Ah minimum battery capacity. Use 24V batteries to match module output voltage and minimize conversion losses.

What's the difference between this HPM module and newer Experion power supplies?
The 51198947-100H uses traditional linear regulation for superior noise immunity, while newer switch-mode units offer higher efficiency. For legacy TDC 3000 systems, the HPM series ensures plug-compatible replacement without firmware updates or configuration changes.

Does the module support hot-swap battery replacement?
Yes, when AC input is present, batteries can be disconnected for replacement without interrupting DC output. The module automatically resumes charging when new batteries are connected. Always verify AC input status via front LED before battery service.

What maintenance intervals are recommended for optimal reliability?
Inspect terminal tightness and check output voltage quarterly. Test battery capacity annually using load bank or discharge tester. Replace batteries every 3-5 years depending on ambient temperature and discharge cycles. Clean ventilation openings semi-annually in dusty environments.
