Key Features
Dual Independent Outputs for Electromagnetic Coil Testing
The SPPS3010-2KD provides two independent adjustable DC output channels, each supporting 0–30V, 0–10A, and up to 300W. This configuration allows users to energize two compatible electromagnetic coils separately or establish different voltage and current conditions for comparative coil evaluation.
Series and Parallel Output for Different Coil Requirements
The power supply supports Independent, Series, and Parallel output modes. Series Output provides up to 0–60V, 0–10A, and 600W, while Parallel Output provides up to 0–30V, 0–20A, and 600W. These configurations offer different voltage and current options for electromagnetic coils with different electrical ratings.
Negative-to-Zero-to-Positive Voltage Output
The SPPS3010-2KD supports Negative Voltage–0–Positive Voltage output mode. This feature provides an additional polarity-related DC output configuration for electromagnetic coil assemblies that require different excitation polarities, such as compatible electromagnets and polarized coil devices.
Precision Encoder for Fine Voltage and Current Adjustment
The precision encoder provides controlled adjustment of output voltage and current. With 10mV voltage setting resolution and 1mA current setting resolution, users can make fine adjustments when establishing electrical excitation conditions for electromagnetic coils.
OCP and OVP Protection Across Output Modes
Over Current Protection (OCP) and Over Voltage Protection (OVP) are available in Dual Channel, Series, and Parallel output modes. These functions help reduce the risk of excessive current or voltage conditions during electromagnetic coil testing and power setup.
Independent Output ON/OFF Control
The Dual Channel, Series, and Parallel modes support Output ON/OFF control. Users can switch the configured output on or off during test setup, making it convenient to connect, disconnect, and restart compatible electromagnetic coils.
8-Group Memory for Repeated Coil Testing
The SPPS3010-2KD provides 8 memory groups:
-
CH1: 2 groups
-
CH2: 2 groups
-
Series Mode: 2 groups
-
Parallel Mode: 2 groups
Frequently used voltage and current settings can be stored and recalled for repeated coil excitation tests and comparative evaluations.
Panel Lock with Buzzer
The Panel Lock Function helps prevent unintended changes to configured output settings during testing. The built-in buzzer provides an audible indication during panel operation, helping users manage repeated bench testing procedures.
Dedicated Series-Parallel Output Port
The dedicated Series-Parallel Output Port allows users to access the combined output configuration without complicated external wiring. Combined with the One-Key Series/Parallel mode button, it makes switching between supported output configurations more convenient.
Applications
Electromagnetic Coil DC Excitation Testing
Provides adjustable DC power for energizing compatible electromagnetic coils. Engineers can set the required voltage and current according to the coil's rated electrical specifications and observe the power supply's output readings during excitation.
Solenoid Coil Testing
Suitable for supplying DC power to compatible solenoid coils during bench evaluation. Adjustable voltage and current allow users to establish different excitation conditions when examining solenoid operation and coil electrical behavior.
Electromagnetic Relay and Contactor Coil Testing
Provides an adjustable DC supply for compatible DC relay and contactor coils. The independent output channels and Output ON/OFF control support coil energization and electrical input condition testing within the rated output range.
Electromagnet Polarity and Excitation Testing
The Negative Voltage–0–Positive Voltage output mode provides an additional configuration for electromagnet assemblies that require different DC excitation polarities. It can be used to establish different polarity conditions when evaluating compatible electromagnetic devices.
Dual Coil Comparison Testing
The two independent output channels allow different DC excitation conditions to be supplied to two compatible coils. This is useful for comparing coil operating current and electrical input conditions under different voltage settings.
High Current Electromagnetic Coil Testing
The Parallel Output mode provides up to 0–30V, 0–20A, and 600W. It offers a higher-current DC power configuration for compatible low-voltage electromagnetic coils that require greater excitation current.
Electromagnetic Device Research and Development
The adjustable voltage and current outputs, together with Independent, Series, and Parallel configurations, provide flexible DC excitation options for electromagnetic device development, engineering evaluation, and prototype testing.
Repeated Coil Testing and Production Inspection
The 8-Group Memory Function allows frequently used voltage and current settings to be stored and recalled. Combined with precision encoder adjustment, Output ON/OFF control, and Panel Lock, it supports repeatable electrical testing and inspection of compatible electromagnetic coils.
