LFM550S & LFM550M Now Available in New B Version – Compact, Lightweight, and Cost-Optimized
More Flexibility, Same High Performance
CINCON has expanded its popular LFM550S and LFM550M series with the introduction of a new B version featuring an open-frame design. This cost-effective alternative to the enclosed C version (with semi-potting) is ideal for space-constrained or weight-sensitive environments.
Key Advantages of the B Version:
- Smaller footprint: Perfect for tight-space installations
- Lower profile & reduced weight: Ideal for lightweight system designs
- More cost-effective: Streamlined for budget-sensitive applications
While lighter and more compact, the B version retains the same 550W output power, high reliability, and advanced protection features of the LFM series. It’s an excellent fit for controlled-environment systems.
