Introducing the New 3VMS Series: Power, Precision, and Performance
We’re excited to announce the launch of our newest additions to the 3VMS voltage monitoring product line: 3VMS-60-208 and 3VMS-60-480. Engineered for reliability and built to handle demanding industrial environments, the 3VMS series delivers enhanced monitoring, smarter protection, and seamless integration into modern electrical systems.
Designed with advanced sensing technology, the 3VMS-60-208 and 3VMS-60-480 provide accurate real‑time voltage measurement, early fault detection, and improved system visibility—helping operators reduce downtime and protect critical equipment. Whether you’re upgrading existing infrastructure or designing new installations, these models offer the performance and flexibility needed for today’s power distribution challenges.
This combination provides multiple advantages for contractors in the field:
1. Faster, Simpler Installations
The 3VMS comes pre‑wired for 208/240V systems, includes a separate 40A contactor, and uses a modular design with field‑replaceable components—all of which significantly reduce installation time.
2. Consolidates Multiple Devices Into One Unit
Instead of installing a standalone voltage monitor + surge protector, contractors get both in a single enclosure.
3. Protects Equipment — Reducing Callbacks
The 3VMS protects motors, compressors, and control boards from the most common power‑related failures:
- Over/under voltage
- Phase loss
- Phase reversal
- Phase unbalance
- Rapid short cycling
- Surge events up to 150 kA
4. Better Diagnostics for Faster Troubleshooting
Contractors benefit from quick, clear fault identification:
- Built‑in LCD display
- Large historical fault memory
- LED diagnostics
- Real‑time voltage readouts
5. Durable, Outdoor‑Ready Construction
The 3VMS series features a NEMA 4X enclosure, making it suitable for harsh outdoor HVAC/R environments. This allows contractors to confidently install this unit in demanding locations without additional weather‑proofing.
6. Long-Term Reliability & Warranty Support
The product includes:
- Limited lifetime warranty
- Up to a 3‑year, $10,000 connected equipment warranty
This gives contractors extra reassurance when recommending the product to customers and reduces liability concerns.
7. Ideal for Both Residential & Commercial HVAC/R
Because the unit supports three‑phase 208/240V or 480V systems, contractors can use the 3VMS series across:
- Rooftop units
- Heat pumps
- Commercial refrigeration
- Motors and pumps
8. Helps Prevent Catastrophic Equipment Damage
By monitoring voltage continuously and disconnecting the load during critical faults, the 3VMS can prevent:
- Burned windings
- Blown boards
- Compressor lockup/failure
- Costly downtime
The new 3VMS series is officially available starting today. View our dedicated landing pages for application guides and detailed product resources.
