They are air insulated, fast response, 6U rack-mount units with tight regulation. A broad range of models is available with output voltage ranges from 0 to 1 kVDC through 0 to 150 kVDC. The LH Series features “air” as the primary dielectric medium. No oil or encapsulation is used to impede serviceability or increase weight. Internal circuitry constantly senses and integrates arcs that occur over a given time. In the event a system or load arcing problem develops and exceeds factory-set parameters, the power supply will cycle off in an attempt to clear the fault and then automatically restart after a preset “off dwell time”. The LH Series’ high voltage output is inhibited for a short period after each load arc to help extinguish the arc. Typically, ripple is less than 0.05% RMS of rated voltage at full load. Off-the-line pulse-width modulation (PWM) provides high efficiency and a reduced parts count for improved reliability. The LH Series’ front panel contains all local control functions like AC power on/off, separate 10-turn controls to set voltage and current levels, HV voltage on and off/reset switches as well as LED indicators for high voltage on, output polarity, interlock, fault status or voltage/current regulating mode. Output levels are indicated by voltage and current digital meters. All voltage and current programming and monitoring signals are coupled to the user interface by true differential amplifiers. This provides for the ability to return the program and monitor commons to ground or system common at the source. This arrangement isolates the return wires and eliminates errors due to unwanted return currents flowing in these connections. The LH Series’ standard operation mode is constant voltage/current. Automatic crossover from constant-voltage to constant-current regulation provides protection against overloads, arcs and short circuits. A rear panel switch allows selection of either constant-current or current-trip operation. Thermostats and fan RPM sensing shut down the power supply due to over-temperature or reduced fan speeds. Standard accessories for the LH Series include a remote interface mating connector and a detachable 2,4 m shielded high voltage coaxial output cable. The LH Series supplies, when configures with the 400 VAC input option, are fully compliant with the following European harmonized EMI directives: EN61010/ IEC61010, Safety EN61000-6-4, Conducted and Radiated Emissions EN61000-6-2:2005, Conducted and Radiated Immunity 2011/65/EU, Restriction of the Use of Hazardous Substances (RoHS) Key Features: 6U Rack Mount Air Insulated Maximum Output Power: 5 kW – Parallelable to 25 kW Maximum Output Voltage: 1 to 150 kVDC Maximum Output Current: 25 mA to 5.0 A Low Ripple: <0.05% RMS of Rated Voltage at Full Load Tight Regulation Static Voltage Regulation: <0.005% for Specified Line and 0.01% for Specified Load Variations, 0.025% for 80 to 100 kVDC Models Current Regulation: <0.2% (8 to 150 kV), <0.5% (1 to 6 kV) From Short Circuit to Rated Voltage at Any Load Condition Constant Voltage/Constant Current Operation Arc Quench & Arc Count Front Panel, Remote, RS232, USB & Optional Ethernet Control Input Voltage: 187 to 228 or 340 to 460 VAC RMS, 48 to 63 Hz, Three Phase Efficiency: >85% Typical at Full Load Output Voltage Accuracy: 0.5% of Setting + 0.2% of Rated Stored Energy: 3.5 to 58 J Voltage Monitor: 0 to +10 VDC Signal for 0 to Rated Voltage Current Monitor: 0 to +10 VDC Signal for 0 to Rated Current Stability: 0.01%/h After 0.5 h Warm-up, 0.05% per 8 h Polarity: Positive, Negative or Reversible Polarity With Respect to Chassis Ground Protection: Against All Overload Conditions, Including Arcs and Short Circuits Signals Provided on the Remote Interface Connector: Differential Voltage & Current Program/Monitor, HV Enable/Status, Safety Interlock, Fault Status, +10 V Reference, I/V Mode Status Options: Blank Front Panel, Zero Start Interlock, Slow Start Ramp, 0 to 5 V Voltage & Current Program/Monitor, Arc Count and Quench, Common to Ground Isolation, Control and Monitor via RS232, USB, Ethernet 3 Year Warranty Approvals: IEC61010-1:2010; EN61000-6-4:2007, Class A EN61000-6-2:2005 Operating Temperature: -20 to +40 °C Dimensions: 265.9 x 482.6 x 609.6 mm Applications: High Voltage, High Power Applications; Photonics; Healthcare (Analytical, Diagnostics, Detectors); Industrial; Semiconductor Manufacturing; Research; Other

Siskiyou's gimbaled lens positioners cover a broad spectrum of optic configurations. The simple 2-axis models are the basis for more complex positioning requirements, including rotational positioning for polarizers or cylindrical lenses. All models use precision rolled 80TPI adjustment screws for pitch/yaw adjustment. The OG series of optical gimbal mounts is a compact and robust mounting platform for laser cavity applications. It uses color coded Soft Touch knob caps in both non-lockable and lockable versions. These knob caps are comfortable to use and provide quick axis location in low light conditions. The LDP laser diode positioner series is ideal for industrial applications.
