PMT HIGH VOLTAGE POWER SUPPLY
- Max Voltage: 2 to 5kV
- Max Current: 1 to 2mA
Integrated power supply for preamplifier
EP series is a high-performance, high-voltage power supply for Photomultiplier Tube (PMT), electron multiplier applications.
Ultra compact size of just 8.35 inches/212 mm width integrated high voltage power supply and power supply for preamplifier ±15 V and ±5 V. The ultra-low ripple noise of as low as 15 mVp-p (high voltage output part) is suitable for PMT and various other applications. In addition, various digital controls are also possible by selecting the -LGob option.

Optical Interface port
This option changes the standard interfaces to built-in optical interface port. By combining this option with an adapter for optical connection (sold separately), communication between the control device and the power supply can be controlled in an isolated state. Be sure to select this option when using the product in the following environments.- -LGob: Optical interface + optical cable 2 meters
- -LGob(Fc5): Optical interface + optical cable 5 meters
- -LGob(Fc10): Optical interface + optical cable 10 meters
- -LGob(Fc20): Optical interface + optical cable 20 meters
- -LGob(Fc40): Optical interface + optical cable 40 meters
Consider selecting the optional optical interface port (-LGob) when operating this DC power supply in the following environments.
- Noisy environments such as factories
(example: when motors or coils are used near loads or power sources). - If this power supply and your controller (PC or PLC) cannot be installed within 2 meters.
- When there is a possibility of arcing or an output short-circuit.
Accessories
- Optical isolation adapter
-
To use the optical interface, you need to prepare an optical interface adapter separately. The following interface adapters are available according to your controller port.
- CO-E32: LAN to optical interface adapter
- USB-OPT: USB to optical interface adapter
- CO-OPT2-9: RS-232C (9 pin) to optical interface adapter
- CO-OPT2-25: RS-232C (25 pin) to optical interface adapter
- CO-OPT4-25: RS-485 (25 pin) to optical interface adapter
- CO-G32: GPIB to optical interface adapter (Scheduled for discontinuation in December 2028)
