--- Quote from: motyr on June 22, 2022, 11:38:29 am ---Hi All, I am looking for recommendation for the high voltage benchtop power supply. It must have at least 600V DC but 1000V would be better, adjustable but not necessary from 0V and the maximum output current of 0.5A (1A will be better). Dual output (like 2x300 ... 2x500V) also acceptable, as long as I can connect them in series to get 2x600V ... 2x1000V. Thanks --- End quote --- I was looking for a DC-supply for our testfield, to generate voltages up to 1500Vdc. Until then we had to connect two or three supplies in series - Not really safe thing for human and machines... ;) Elektro-Automatic got superb hv-supplies, but with more current we need, therefore more power - And more money to spend for. Finally I´ve found a suitable supply in the USA, from Magna Power: https://magna-power.com/products/magnadc/sl I´ve ordered 0-1500Vdc, 1 A - Perfect for our needs (testing/adjusting DC-Link supervision circuits). And the price.... Appx. 2500$ only. Will arrive next week. Martin |

Two well-known specialist brands in the field of HV power supplies - those that start at 1kV - are Spellman HV and Glassman HV in the USA. If tubes are preferred, Universal Voltronics would be another brand. if 600V is enough, Sorensen, AMREL, Ametek, TDK are also good bets. All these brands make reliable units used in industrial, military and medical applications and are therefore rackmounted and very robustly built. Due to the dangers of high voltage, many have multiple interlocks built in as well as special connectors to deter unintentional use or accidents from untrained users. Many were customized and interlocks are difficult to defeat. For my tube tester build pictured below, I used Glassman and Amrel to supply up to 3kV to the plate and grids and a Rohde & Schwarz linear supply for the filament. Spellman HV is still independent but Glassman HV was acquired by XP Power. Universal Voltronics was also acquired but I do not think they make HV power supplies anymore. There are good deals to be found from time to time on eBay especially if you know how to make them work properly. |

I bought a HSPY 1000V 0.5A. Works very well for what I used it for. Some work on electronic tubes and recently had use for it to repair a 300 V DC to 18 + 9 + 5 V DC switched mode power supply module. Can recommend that. I am extremely careful when using it. Not because of build quality, but that it easily can kill people! |

How about one of these. 0-2500vdc, 0-250mA, voltage current and power limits. Several available on EBay now for under $100us. |
