Triple Power Supply HM8040-2 3 independent DC Supply Voltages 2x0-20V, 0.5A; 1x5V, 1A Floating Outputs Digital Display for Voltage and Current Adjustable Current Limiter Parallel and Serial Operation The compact Power Supply HM8040-2 was developed mainly to supply power to laboratory test systems. The use of this instrument has become more and more popular in technical schools and institutions. The HM8040-2 utilizes conventional design technology with a linear series regulator assuring dependable and low-noise output power. The 3 floating, independent output voltages provide a maximum capacity of 25Watts. In addition to the two continuously varia- ble outputs of 0 - 20V, the HM8040-2 offers a 5V output which is adjustable by ±0.5V and is a useful feature when working with TTL level circuits. Current limiting for both Specifications (Reference Temperature: 23°C ± 1°C) Output Voltages: 2x0-20V, continuously variable 1x5V, variable ±0.5V Voltages 2x0-20V: Range: 0-20V, continuously variable by means of coarse and fine controls Resolution: ≤0.1% Internal resistance: ≤15mΩ (typ. 7mΩ) Stability: ≤2.5mV (I max.: 2x200mA) at line voltage variations of up to 10% Recovery time: ≤80µs Load regulation: ≤0.05% Temperature coefficient: ≤0.1%/°C Ripple and noise: ≤1mV Output current: max. 0.5A Current limit: 10mA to 500mA continuously adjustable Resolution: <1% Voltage +5V: Range: 5V, variable ±0.5V Internal resistance: ≤0.05Ω Stability: ≤5mV at line voltage variations of up to 10% Recovery time: ≤100µs Sous réserve de modifications / Reservado el derecho de modificación 20V ranges is continuously adjustable. Transition from voltage to current control is automatic and clearly indicated. Each 3-digit display is individually switchable from voltage to current measurement and all outputs can be switched off (or on) simultaneously, at the push of a button. Series or parallel mode is possible in all voltage ranges. In addition to low residual ripple and noise as well as excellent line and load regulation, the HM8040-2 provides all protective circuitry necessary to ensure problem-free operation. This Power Supply will provide an affordable alternative to more expensive laboratory instruments. Use only one HM8040-2 with any other module in a HM8001-2 Mainframe. Temperature coefficient: ≤0.1%/°C Ripple and noise: ≤5mV Output current: max. 1A Display: Two 3-digit 7-segment LED-displays Indication for V and mA (selectable) Current limit indicator General Information: All outputs floating Series connection of all outputs possible Outputs switchable from front panel Built in overheating protection Supply voltages: (from HM8001): 1x8V ~ 0.32A 2x24V = 0.5A 1x5V = 1A ∑ = 32W max. Operating conditions: +10°C to +40°C max. relative humidity: 80% Dimensions (without 22-pin flat connector): W 135, H 68, D 228mm Weight: approx. 1.2kg Values without tolerances are meant to be guidelines and represent characteristics of the average instrument. 11 Previous Page Next Page
