Model 1449M/1449ME

 GENERAL

 HV Module Slots per Mainframe: 16.
 Channels per Mainframe: Up to 256.
 Maximum HV Output Power: 1.6 kW for Model 1449M;
 800 W for Model 1449ME; for each plug-in module in excess
 of eight, deduct 15 W from the 800 W available.
 Ramp Rates: The HV run-up  and  run-down  rates  may  be
 selected by a jumper option and/or software on the 1445 or
 1445A control units between 10-500 V/sec.

 DISPLAY AND CONTROL

 HV Enable Indicator Switch: Yellow lamp indicates HV is
 ready for turn on (i.e., HV Disable is not actuated and INTER-
 LOCK is not asserted).  Integral with front-panel HV ON indi-
 cator (red lamp) and HV Enable button.  Rear-panel indicator
 lamp.
 Input Power Status: Model 1445A -  three  LEDs  indicate
 presence of +5 V, +1 5 V, and -1 5 V. Model 1445 - two LEDs
 indicate presence of -1 5 V and +5 V. Active lit by +1 5 V.
 System Active/ENB:  Front-panel  LED  indicates  modules
 enabled for generating HV.
 Status: Lemo connector, TTL high = HV on, low = HV  off.
 Interlock: BNC connector, TTL high = on, low = off.
 HV Limit Potentiometers: Set separate positive and nega-
 tive hardware limits.

 PROTECTION

 System Protection: In the event of a power failure, the
 system will shut down in an controlled manner.  A front-panel
 switch on the 1440 mainframe provides immediate shut down.
 Panic-off in the rear is accomplished by pulling out the power
 cord.  An interlock is provided on the control unit that will
 disable all HV in the mainframe when driven to ground.
 Thermal Protection: A temperature monitor on each of the
 low voltage power supplies shuts off the high voltage in the
 event of overheating that can result from excessive loading,
 clogged fan filters, or high ambient air temperatures.

 MECHANICAL
