*New MW9H flashtubes supplied with M11 light units handle up to 1200Ws.
The MW9M flashtubes have a maximum capacity of 1000Ws.
OPERATING INSTRUCTIONS
Operation of Brown Line power supplies is simple and straight forward. It is suggest-
ed that this sequence of operation be utilized for maximum life and dependability.
Make sure that the Model and Power switches are in the off position and the Push to
Reset buttons are fully depressed into their sockets. Connect light head cable(s) to the
Light Unit Outlet(s) on the power supply. The outlets are wired in parallel so it does not
matter in what sequence light head cables are connected.
Never connect or disconnect light units while power is on. Do not insert or remove
flash tubes while power is on. Your Brown Line power supply is equipped with
arc-protection, but should your light unit or power supply malfunction, or the power
cord, or even the internal wiring in the studio be improperly terminated or defective, the
chance of arc-over when connecting or disconnecting light units is greatly increased.
Severe power supply damage and operator injury may result if arc-over occurs when
light units are being disconnected or connected. To prevent this, you should always turn
the power supply off when disconnecting or connecting light heads.
Never subject a flash tube to more watt-seconds than it is designed to handle. MW3
and M90 series (non-”Q”) light units have a maximum rating of 400Ws, while “Q” ver-
sions are rated at 1200Ws. M11 light units are rated at 1200Ws* (with new MW9H
flashtube) and M11Q light units are rated at 2400Ws. We strongly recommend that at
least one light unit in your system is capable of handling the maximum output of your
power supply. If you are not sure if your flash tube and light unit can handle the power
provided by the set up you are using, check pages 25 and 26 and the Power Distribution
Chart on the side of your power supply.
Connect AC power cord into Power Input on power supply, then plug into a properly
grounded outlet. Use proper 3-conductor grounded cord for operator safety and to
reduce self-firing caused by static electricity. Set Full/Half switch as desired. This switch
reduces the total output of the power supply. The difference between the “full” and
“half” settings is one f-stop. After flashing, do not switch the Full/Half switch until ready
light is illuminated, or until at least ten seconds after turning off unit. Failure to follow
this procedure may result in damage to the switch.
Plug sync connector into Sync socket and connect the other end to PC cord for camera.
Once the camera is connected, tripping the shutter will automatically trigger the flash.
A slave tripper (Speedotron #23510), may be inserted into the Sync socket in place of
the PC cord. In this mode of operation, the slave will activate the power supply when it
senses a bright flash of light from another light source. If the power supply fails to flash
when exposed to another light source with the slave installed in the sync socket, it may
be necessary to remove the slave, rotate it 180° and reinstall it into the Sync socket.
DESCRIPTION OF CONTROLS
Power – turns power supply on and off (flashes units when turning off D802 or D402).
Model – turns model lamp(s) on and off.
Symmetrical/Asymmetrical – controls power distribution. In the symmetrical position,
power is split equally between all lights. In the asymmetrical position, power is
distributed unequally and model lamp brightness on light units in outlets 3 and 4 is
reduced.
Full/Half – controls amount of power delivered to light unit outlets.
Ready/Push to Flash – a combination ready light and test flash button. Illuminates to
indicate when power supply has recycled to 85%. Pressing the button when
illuminated triggers the flash for testing or open flash applications.
Sync – socket for sync extension or slave.
Push to Reset – resets circuit breaker. Circuit breaker disables power supply in case of
malfunction.
Power Input – socket for AC power cord.
Light Unit Outlets (4) – sockets for connecting from one to four light units to power
supply.
