3005 B
30V / 5A Linear DC Regulated Power Supply with Output On/Off
0–30 V, 0–5 A linear DC power supply — 4-digit LED display, Output On/Off pause function, CV/CC, short-circuit protection.
— Vartech® DC Power Supplies
3-channel linear DC supply — 0–30 V / 0–5 A × 2 variable + 5 V / 3 A fixed, with 5-turn precision pot, 4 LED displays and Output On/Off.
The Vartech 3005-3 D2 is a triple-output transformer-based linear DC regulated power supply with three independent channels: two fully variable 0–30 V / 0–5 A channels and one fixed 5 V / 3 A output. A 5-turn multiturn potentiometer provides precise voltage control on the variable channels. Outputs can be used independently, in series or in parallel. The unit features 4 LED DPMs, Output On/Off switch, and automatic CV/CC switching on the variable channels.
