SR3

SR3 Series Stealth Microwave’s 19 inch rack mount housings are designed to fit any of Stealth’s current models. The SR3 Series adds many benefits over our standard module format. LEDs on the front panel monitor normal operation, thermal or power cautions, and alarms for thermal shutdown, amplifier, VSWR, and fan failures. The SR series comes standard with a USER PORT (DB15) which provides TTL signals to monitor the amplifier’s status. The User Port provides analog voltages to indicate the forward and reflected power levels at the output of the unit and also provides amplifier status and alarm conditions. An RS-232 interface that performs the functions of the USER PORT is also available. Features • LED amplifier status and alarm display • Built in AC or DC power supplies • Forced air cooling with hot swappable fans • On/off control via a BNC connector • DB15 Monitoring/control connection standard Options • RS-232 interface • Gain Control Environmental Characteristics Operating Temperature (Ambient): 0o C to 40o C Humidity: 95% relative without condensation Altitude: 30,000 ft.

If amplifier has shut off due to OVER TEMP condition, LED will remain off until module reaches safe temperature Amplifier’s temperature exceeds + 65 °C Amplifier’s temperature exceeds + 75 °C. The unit is shut off and will not turn back on until its temperature drops below + 65 °C Amp failure. Excessive output VSWR. Possible antenna problem. Fan failure. The fan is either locked or not connected to power. 1007 Whitehead Road Ext., Trenton, NJ 08638 Tel: (609) 538-8586 ♦ Fax: (609) 538-8587 Email: sales@stealthmicrowave.com ♦ Web site: www.stealthmicrowave.com SR3 Series REAR PANEL DETAIL F2 RS-232 AMP CNTL LINE F1 RF OUT RF IN RF SAMPLE USER PORT Label RF OUT RF IN RF SAMPLE F1 F2 RS-232 USER PORT AMP CNTL LINE Function 50Ω RF output.
