Operating at a frequency range of 1.8MHz to 2.17MHz, these ENI GMW 25Z have the DSP-based control module which automatically measures forward RF power and reflected RF power, maintaining constant power output with in ±1% of set point over a Dynamic Power Range of 25 to 2500 Watts.

GMW 25Z Specifications

• RF output frequency: 2.00 MHz
• RF output power rating into matched load: 2500W into a 50Ω load
• RF output power rating into mismatched load (all Φ):
  
  

  Forward Power	Load VSWR
  2500W	1.5:1
  2000W	2.0:1
  1500W	3.0:1
  500W	∞:1

  
  
• Dynamic power range: 5-2500W
• Load impedance range: Unlimited
• RF stability/spurious output: Unconditionally stable / < -50dBc (for any load, within ratings)
• Harmonic output/ distortion: <-40dBc (within ratings)
• Power control/ regulation:
  AC line-to-power 0.5% max. change in output power over rated line voltage range.
  Regulation tolerance is referenced from set point. Subject to limits of forward & reverse power and current; accuracy relative to ENI power standard.
  
  

  Power Range	Reg. Tolerance
