The Elenco Precision Quad Power Four Linear Regulated Supplies (Model XP-581A) is a benchtop power supply instrument delivering four independent, fully regulated DC outputs for laboratory and service shop environments. It combines fixed voltage rails with a variable output stage, analog metering, and comprehensive protection to support electronic development, testing, and troubleshooting across diverse voltage and current requirements.
Technical Specifications
Output Configuration
• +5 VDC @ 3A (fixed)
• +12 VDC @ 1A (fixed)
• −12 VDC @ 1A (fixed)
• 0–20 VDC @ 2A (variable)
Protection & Regulation
All four supplies feature thermal shutdown, current limiting, and short-circuit protection with precise voltage regulation across operating conditions.
Metering
Dual analog meters provide real-time voltage and current monitoring on the variable output stage.
Series Operation
The fixed rails support series stacking: −12 V and +12 V combine for 24 VDC @ 1A; −12 V and variable output produce 12–32 VDC @ 1A. All outputs share common ground.
AC Input
User-selectable 115 VAC or 230 VAC. Fuse protection: 2A @ 250V (Part # 533020) for 115VAC; 1A @ 250V (Part # 533010) for 230VAC.
– Key Features
• Four independent output channels with common ground architecture
• Analog metering for real-time load and voltage observation
• Flexible series connection capability for extended voltage ranges
• Dual-voltage AC input support for global compatibility
• Dedicated thermal and short-circuit safeguards on all rails
• Compact benchtop form factor: 10.2″ W × 3.7″ H × 10″ D, 8.11 lbs
• Metal chassis with front-panel controls and binding post terminals
– Typical Applications
Circuit development and validation, device characterization, analog and mixed-signal troubleshooting, educational laboratory work, and field service environments requiring simultaneous multi-voltage power distribution.
– Compatibility & Integration
Standard binding post output terminals accept common test leads and probe interfaces. IEC-standard AC inlet accommodates regional power configurations (115 VAC or 230 VAC selectable). Operates within 0–40°C ambient and up to 90% relative humidity in indoor environments.
