Reference data. These figures describe a comparable published unit, not necessarily the exact unit supplied. The full specification — guaranteed losses, impedance, dimensions and dimensional drawing — is confirmed in your written quote before you commit to an order. Sound levels are NEMA TR-1 maximum limits. Reference losses are not a statement of DOE compliance.
