oem-tech 100W FLD-nano Flashlamp Driver
Overview
FLD-nano is a compact but powerful flashlamp driver designed for air-cooled flashlamps similar to the depicted below.
Driver charges the external capacitor bank up to required voltage and then, following the external TTL signal, initiates the discharge by applying the trigger pulse (400V by default) to the flashlamp. FLD-nano requires +24 V DC power supply and pulse generator to set an operating frequency. An output voltage level can be programmed in working range by user either manually (through onboard configuration trimpot) or remotely (applying a DC voltage to the respective pin). The driver maximal output power could be decreased, if needed, by on-board trimpot.
Applications
- UV polymerization
- UV sterilization
- Sintering
- Annealing
- Stroboscopy
Main parameters
- 24V DC input
- 100 W average output power
- Up to 1000 V output voltage (to the capacitor bank)
- External triggering, no simmer
Appearance
Connections, signals, signal descriptions
FLD-nano can be controlled in manual mode. In this case, jumper is set between PINs 1 and 2 of INTERFACE connector in order to use VOLTAGE PROGRAM trimpot. To obtain a trigger pulse immediately after charging a storage capacitor to output voltage level (manual autorun mode), set a jumper between PINs 8 and 7. ENABLE jumper between PINs 5 and 6 allows the driver to run. It could be convenient to interconnect PINs 5 and 6 using a button instead of jumper. Other possibility to control FLD-nano is to use an external controlling device, which sets the storage capacitor voltage level (0-5V to PIN 1) and sends TTL pulses to PIN 8 to initiate pulses to trigger transformer.
24V DC INPUT: Molex SPOX (0965-2048)
INTERFACE: Molex C-Grid III (90130-1210)
HV OUTPUT: Molex MiniFit (3928-1023) or flying leads
TRIGGER: Molex MiniFit (3928-1023) or flying leads
Other elements
- VOLTAGE PROGRAM trimpot – sets output voltage in Stand-alone mode
- POWER LEVEL trimpot – allows to adjust the maximum output power of the driver (for example to reduce input current in low power applications)
- FAULT LED – indicates the drivers failure (overheating)
Grounding and mounting
- Grounding policy By default INTERFACE return, 24VDC INPUT negative, HV OUTPUT negative are interconnected to each other.
- Driver is to be mounted with four M3 screws.
System layout
Recommended system layout is shown below
Operations (in manual regime)
- Ensure that FLD-nano is disconnected from the power source.
- Connect storage capacitor (e.g. 33uF/1000V) to FLD-nano.
- Connect your flashlamp to storage capacitor.
- Connect trigger transformer to FLD-nano and to flashlamp.
- Ensure that all jumpers of FLD-nano are removed.
- Connect 24V DC power supply to FLD-nano and apply 24V DC power to FLD-nano.
- Set on VOLTAGE PROGRAM jumper (i.e. place jumper between PINs 1 and 2 of INTERFACE), now the output voltage to storage capacitor is regulated by VOLTAGE PROGRAM trimpot.
- Set on a jumper between PINs 3 and 4 of INTERFACE to short-circuit IDC signal and allow the operations.
- Set on a jumper between PINs 7 and 8 of INTERFACE to switch FLD-nano in autorun mode when the flash is initiated immediately after the capacitor bank is charger up to the required voltage.
- Interconnect PINs 5 and 6 of INTERFACE by any way (a jumper, a button) to enable the outputs of FLD-nano and start flashes.
Important note Power/Enable start-up sequence is important. FLD-nano must be powered first and enabled after then only. If FLD-nano is already enabled at the moment of power-up, this will be considered as a fault and the driver won’t start the operations.
