RF Power:

Frequency 13.56 MHz
Frequency Stability ± 0.005%
Impedance 50Ω
Connector Type 'HN'
Power Rating 2500W into a 50Ω load
Regulation Modes 0 - 2500 W (via Front Panel Controls)
  0 - 2750 W (via ANALOG REMOTE Interface)
  0 - 2500 W (via DIGITAL REMOTE Interface)
Regulation Tolerance 1:1 ≤ Load VSWR ≤ 3:1
  ±2% (for 200 W ≤ set point ≤2750 W)
  ±4W (for set point <200 W)
Harmonic Distortion < -55 dBc
Line Related Noise < -55 dBc (at rated power)
Non-Harmonic Spurious < -60 dBc
AC Line-to-Power Regulation ± 0.5%
Power Output Meter 0 – 3000 W digital display with an accuracy of ±2% of power output. Simultaneous forward & reverse or load & reverse power indications.
Automatic FWD/LOAD Power LEVELING 2 W to maximum power output operating into any load within power foldback limits, locally or remotely controlled.
Power Foldback Protection Automatic; occurs when reverse power reaches 500 W or power amplifier current exceeds preset limit.
Pulsed Operation Rise time is less than 3.0 ms; RF output may be controlled simultaneously for amplitude and pulse width by pulsing the RF power set point.
Load Mismatch Tolerance The units will operate continuously into any load mismatch without oscillation or failure.
AC Input
Ratings 3/PE~, 200-220V ± 10% 27A, 50-60Hz ±3Hz(No tap selection necessary)
Connection 10 AWG, 4-Conductor AC power cord with no plug and no terminations. The green wire is connected to the generator chassis and serves as the Protective Earth (Ground) conductor for the unit. This conductor must be correspondingly connected to frame ground through the AC distribution panel of the system. Refer to Section 2.3 AC Input for further details.
DIGITAL REMOTE Interface 9-pin "D" subminiature type RFI suppression receptacle.
ANALOG REMOTE Interface 36-pin miniature-ribbon type RFI suppression receptacle, per customer requirement.
External RF ON/OFF Control HCTTL-compatible; closure to ground activates RF ON.
Forward Power Control (Analog Remote) 250 W/V factory calibration (i.e., 10 V = 2500 W)
Maximum RF Power Indicator/td> Enunciated in STATUS field on VF DISPLAY.
RF Power ON Signal Open collector, transistor output; external pull-up voltage, 30 V maximum.
Reverse RF Power Indicator Reading within 1 - 500 W range; 50 W/V factory calibration (i.e., 10 V = 500 W); Accuracy:± (2% of reading + 10 W)
Forward RF Power Indicator Reading within 1 – 3000 W range; 250 W/V factory calibration(i.e., 10 V = 2500 W); Accuracy: ±2% (200 W ≤ set point ≤2625W) ±4 W (set point < 200W)
Maximum Operating Altitude 2000 m (6562 ft.) above sea-level
Cooling System Combination of water-cooling and forced-air cooling.
Cooling Water
Inlet Temperature Rating 5-35°C (41-95°F)
Pressure Maximum 480 kPa (70 PSI)
Flow Rate Minimum 7.0 ltr/min. (1.8 gal./min.)
Connections Accept 1⁄4” male (NPT) pipe thread
External Ambient Air
Temperature Rating 5-40°C (41-104°F)
Relative Humidity Rating 80% RH (max.) at up to 31 °C (88 °F), de-rated linearly to 50% RH (max.) at 40 °C (104 °F)
Installation (Overvoltage) Category INSTALLATION CATEGORY II: Local level, appliances, portable equipment, etc., with smaller transient overvoltages than distribution level and fixed equipment.
Pollution Degree POLLUTION DEGREE 2: Normally only non-conductive pollution occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected.
