Product Description

Model Number Interpretation

• 1: First‑generation dynamic braking platform

• DB: Dynamic Braking unit

• 2: 200/230VAC voltage class (three‑phase)

• 005: 5HP power rating (compatible with 5HP drives)

Technical Specifications

• Input Voltage: Three‑phase 200/230VAC ±10%, 50/60Hz

• Power Rating: 5HP (3.7kW), continuous braking duty

• Braking Resistor: Internal, optimized for 5HP motor deceleration

• Enclosure: NEMA 1, IP20 (indoor use only)

• Protection: Overvoltage, overcurrent, overtemperature, short‑circuit protection

• Ambient Conditions: 0–45°C, 5%–95% RH (non‑condensing)

• Weight: Approximately 12.7kg (28lb)

• Certifications: UL, CSA listed

Interface and Communication Configuration

• Power Terminals: L1/L2/L3 (three‑phase input from drive DC bus), PE (protective earth)

• Control Terminals: Braking enable input (dry contact from drive), fault output relay (250VAC/5A for overtemp/overvoltage)

• Communication: No onboard communication ports; hardwired interlock with drive only

• Indicators: Two LEDs; green for power/standby, red for braking active/fault

Core Functions

• Absorbs regenerative energy from 5HP motors during rapid deceleration or overhauling loads, preventing drive DC bus overvoltage faults

• Reduces motor stopping time significantly compared to coast‑to‑stop

• Internal braking resistors eliminate need for external resistor banks, simplifying installation

• Seamless integration with Reliance SP500/GP‑1200 series 200/230VAC 5HP drives

• Comprehensive thermal and electrical protection safeguards the unit and connected drive

Application Scenarios

• 5HP conveyors, cranes, hoists, mixers, and fans requiring fast, controlled stopping

• Overhauling load applications (e.g., inclined conveyors, vertical lifts) using 200/230VAC three‑phase power

• Retrofit projects for legacy Reliance drive systems needing enhanced braking performance

• Light‑to‑medium manufacturing, commercial HVAC, and material handling systems

Usage and Maintenance Instructions

• Mount vertically in a clean, dry, well‑ventilated indoor area with 150mm clearance top/bottom for cooling airflow

• Use rated copper conductors for power wiring; separate power and control cables to minimize EMI

• Connect braking enable signal from drive to ensure coordinated operation

• Inspect all terminals and wiring quarterly for looseness, corrosion, or overheating signs

• Disconnect all power before cleaning; use a dry cloth only—avoid liquids or chemical cleaners

• Monitor LED indicators during operation; resolve red fault conditions before restarting the system

• Avoid static discharge when handling; do not disassemble the unit without professional guidance

• Store spare units in a cool, dry, dust‑free environment
