24VDC Loop Power Supply Operation Manual 2 BATTERIES The 24VDCPS uses 2 AA batteries. Recommended batteries are Lithium (non-rechargeable), Alkaline, or NiMH (rechargeable). To avoid damage by over-dis- charging, rechargeable batteries should be removed when the Low Battery LED () illuminates. Non-Rechargeable batteries may continue to be used until the Red Fault LED () illuminates, at which time the output voltage will have fallen below 24 V. Lithium batteries are recommended for best performance in cold weather operations. Typical Battery Life (Conditions: 12 mA loop current, 23° C)...
